We can do THIS now! - Lumafield CT Scanner

Heck,

this

look inside the Apple Vision Pro allows us to learn things that would otherwise be nearly impossible without destroying the device, but the Neptune CT

scanner

Luma Field just lent us does a lot more than just spit out a 2D image like

this

. can stitch hundreds or even thousands of 2D X-rays into a complete 3D model. Come and take a look. Look at this. Here are all the small magnets for the optional Zeiss lenses. Here are the worm gears for automatic IPD adjustment. I actually got a really cool one where we isolated those components so we can see the whole mechanism and if you look closely at this view you can see every single BGA solder joint on the chips on the board, pretty impressive for not removing any of them. the screws. which, by the way, are much easier to find now if we wanted to take the iix it approach and depending on the setting which we'll talk about in more depth later, we can even get close enough.

Look at this, look at this. Look at this, we can see this message from our sponsor, Thorum. Check out their Rings watches and necklaces made from unique materials like gibian meteorite and ethically sourced antlers. You can check them out at the link below and use the code LT to get 20% off without Looking too closely at the spoilers behind me, let's do it again but this time with a Sony dual sense controller because it really shows off so much power Like the versatility of the Neptune CT

scanner

as before, we mounted our device on foam chuck. into the machine, close the hatch and activate the x-rays.

I don't think that's going to go out of style once everything is done, let's get this view. You can think of this less as an image and more of a controller shadow, but instead of a light shadow, it's an x-ray shadow, so the lighter areas here are where less dense materials like plastic allow the Much of the x-ray radiation passes to our sensor. Darker areas like these are the denser parts, usually metallic. like these screws or these giant vibration motors that block our photons much more effectively, then we take hundreds of these images from different angles and upload them to Luma Field's Voyager Cloud platform, which does a bunch of calculations to spit this out and I don't think This will ever become obsolete, this is great, this scan would have taken a couple of hours and in fact, you can see here that we can review all the raw x-rays that made up our 3D image and then moving the slider attenuation we can see the different densities of materials in the controller, for example if we slide it all the way we can see the air around the controller and then going to the other side first the plastic is removed and then we can continue.

Until it is broken down into just steel and welding, it offers a number of different views that can be extremely useful depending on what you want to see. The one we're looking at here allows us to go through the controller layer by layer so we can see the exact density of the capacitors on the trackpad, for example, we can see the battery rolls, something that definitely can't be safely examined under circumstances. normal, and we can even look inside the rumbling engine to see how it's built, that's so cool. We've been having an absolute field day scanning basically everything that fits in the machine, like this Buzz Lightyear from the TCH Family Store.

Oh, look, there are the two infinite larynxes of him and beyond. We also made this high heel shoe when We're trying to figure out how to mount an adorable scary mouth on the bottom on a ubiquitous access point to take a look at its antenna setup and this power supply to see if we can use Neptune to non-destructively inspect the quality of solder joints. the answer is pretty much is, but let's back up a bit, aren't CT scanners for medical applications and why doesn't this one look like a donut? While the fundamental principles are the same between the Luma field and a medical CT scanner, there is one.

The main difference between the two in the Luma field is that we rotate the object, whereas in a medical CT scanner we rotate the scanner itself. Also, those things tear and for good reason, humans are not good at staying still for long and this is especially true for your heart and lungs, so a human scanner should be able to do a full scan. of 360° in a fraction of a second or blurred motion of your organs doing inconvenient things like keeping you alive will ruin the image, another reason Medical CT scans go so fast that the radiation is an x-ray machine that creates ionizing radiation that potentially It can lead to problems like cancer if exposed for too long, so doctors are usually willing to give up some accuracy of AC if it reduces a patient's lifespan.

Finally it has to stay there, since humans are not particularly dense. Medical CT scanners are also not particularly powerful. The Luma field, on the other hand, is powerful enough to see through steel, so don't put your hand on any non-living objects here. like this screwdriver available at LTT store.com they don't move unexpectedly and can be exposed to very good for industrial CT scanning, since its extremely low density makes it practically invisible in our scans. One note is that it is very important to place objects at a slight angle because flat surfaces cannot be seen if they are parallel. the x rays now that we have our object secured we can place it on the table and start setting up our scan what we want to do is align it as best we can with our x ray emitter the x rays come out here and cross the machine in a cone shape to that we get the highest detail very close to the emitter right here oh, I pumped it with my shoulder, God, we get the highest detail very close to the emitter right here and as you just saw the table can be reconfigured, it can be moved up, down, left, right and move closer and further away from the transmitter.

The problem with being close is that we sacrifice the maximum size of the object to be able to do something like this over here, but if we wanted to scan something like Here we can be as big as Buzz, but it will have to go very far back in the camera and we're going to hit some details after the X-rays pass through our object, they will hit this piece of carbon fiber called here. Scintillator The scintillator converts our X-rays into visible light for two reasons: The first reason is that X-rays are famous for passing through things including image sensors.

I guess that's bad, yes that is proven and two image detectors for visible light are cheap. like cheap phones, they have three cheap ones, so ctil lator is anyway, we can assume the screwdriver will look good here, close the door and take a look at it, see what the odds are that I got this right, oh, I didn't, but Hey, remember this, now that we've made sure that we're not going to clip our object in the entire rotation range, we're going to go ahead and set our scan parameters to 10 minutes, this is going to be a pretty difficult process . one and then we click optimize and start scanning now for most of the scans we do here, the machine will take 900 individual x-rays, rotate the object slightly, and then stop for each exposure.

Super fast scans like the one we're doing right. Now, however, we're going to keep the center table rotating slowly throughout the scan to save some time. Hey, it's done, which I guess begs the question: Was it safe for us to be standing here while he did that? rays, you know, radiation, okay, first I just want to clarify that although the Luma field produces ionizing radiation, it is not radioactive, which means that by the time the beam is turned off, there is no radiation from both the machine and of whatever is inside it. The only real concern is preventing the To unload this thing on the back there are three 8 inch lead plates and then around all the other sides there is 1/4 inch of lead, all of which is checked during installation for no radiation leaks;

In fact, there is so much lead around this thing that while the scanner is on, you can stand right next to it and experience a reduction in the amount of radiation you are receiving because it will block the radiation from the Sun, the radioactive materials in the ground below. of you and even that banana that is your colleague. Eating my devious plan to poison Linus is thwarted again and so is his gut. Wow, all things considered, the quality of this is pretty okay, obviously not as good as the longer scans, but between the Reconstruction and the raw x-rays there's a good chance. that even a quick scan like this can tell us what we want to know, like we can see that a little bit is missing, so we manage to detect it, but there's also a lot that this scan can't tell us, like you can see the plastic around the tips here it's kind of a mess and there's no real detail on the ratcheting mechanism, so let's try this again, but this time we're going to play with the manual setting first, the main reason for the plastic in our first scan.

It seems so strange is a phenomenon called beam hardening. The X Source in our Luma field produces polychromatic X-rays, meaning we have a range of low and high energy photons shooting through the scanner. The problem is low energy. photons are absorbed first while high energy photons pass through, meaning that the first layer of material will always appear darker than the last bit of material, which can cause some of the oddities we just saw. There are two main ways to avoid this. The first is to use monochromatic x-rays where all the light emitted has the same energy level, but unfortunately achieving this requires a synchrotron or linear accelerator.

Why do they sound so expensive? Because they are. Instead, the Luma field simply removes them. most low energy photons using one of the copper filters you'll see, there we go on this wheel here, they range from 0.5mm to 6mm, depending on how hard you want the beam, the offset However, The thicker the filter, the less exposed the image will be, meaning the scan time needs to be increased. It's actually quite similar to how an ND filter works on a film camera, which, if you think about it, can be said. all the settings in the Luma field let's set the screwdriver scan again, but this time manually, exposure time 46 seconds 2 and 1/2 mm and scan, scan whatever, it doesn't really matter because we're going to film Magic this thing. cooking show Trick, later we got this, there's still a bit of weirdness in the plastic, but our better display setup has given us a much better look at the inside, especially the metal parts of the screwdriver that we can now see inside the ratchet and We can tell how far the press fit parts are inserted, we can also see exactly where the magnet ended up on the shaft and we can even see the individual teeth on the ratchet.

These are all things that weren't as evident in a quick 10-minute scan with That said, to get good results you don't always need to spend 12 hours irradiating the screwdriver, but it turns out that's a particularly difficult example, thanks to the steel and plastic which are very close together for an entirely plastic piece, you can get great results in half. an hour with aluminum parts taking 4+ hours and steel, okay yes anything containing steel is probably best left overnight but this raises a big question besides looking really cool what is the point of all this and who needs one?

The most obvious is to look at the inside of an assembled part for things that can only be seen while it is being assembled, such as the crushing of an O-ring or how much the battery pins compress once the lid is closed. It's also cool. To validate injection molding or c casting, like you can check for bubbles inside an alternator housing and you can see the deviation between the finished part and what was originally designed in the software, there is one thing we need to clarify , although it is unlikely that we will. It is possible to damage electronic components by viewing them in the Luma field after being exposed to ionizing radiation for a couple of hours.

Bits can get flipped in flash memory and if that happens to the wrong bit, either your phone's storage or the BIOS. chip in your GPU, whatever it is, won't work. Fortunately, Luma Field has looked into this and has a helpful article onhow to calculate safe exposure levels to ensure our phones and our GPUs come out as happy as clams as to exactly what we're going to use the Luma field for, well I don't know guys, the sky's kind of the limit here or well, about the size of a basketball is the real limit, oh, and also the materials, gold.

It turns out that it's too dense to get through, but none of those limitations have stopped us from making good use of it. Things we've scanned so far include this pan sorus prototype that we analyzed to validate the factory glue application with this huge Phillips head. Bit that we printed on our Ridia metal 3D printer, the Luma field allowed us to verify that the dimensions are correct and also that the part is mechanically sound on the outside and, in Oh, we used it to observe the hinge mechanism of the fold of pixels we scan. a handful of computer mice whose insides often can't be seen without destroying them, and this scan of a GPU is now available on the LTT Labs website, giving us a great look at the processor size, memory chip layout, and cooler design without needing to remove the factory heatsink, which could invalidate future thermal tests, what really catches your eye is not the functionality CT scanners have been around for decades, it's the price now, it's a subscription, which I know, but the Neptune starts at $75,000 a year and includes their Voyager software that handles all the rebuilding.

That sounds very expensive because it is, but it starts to seem a lot more reasonable when you consider that many industrial CT scanners are going to require a full-time technician to operate them, which will cost you over $7,000 a year before you pay. . In fact, I bought a million-quarter doll machine. I've also said many times in the past that while I don't like subscriptions, I don't mind them as long as they give me the option to buy the machine outright and Luma Field does the job. The price is, well, if you have to ask, but it's aimed at customers who work with sensitive information and want to do all the processing in-house, which really sounds like it would be a really cool future video, an F GPU to go crazy about.

Process this anyway, it feels a little strange to say we're going to have a link below to get one of these, but some of you probably work in R&D or manufacturing and are probably already thinking about how long this is going to take. This might save you and then I guess for everyone else, I don't know, we'll link some of our scans so you can see them and in the comments below let us know what you want us to scan next, just like me. We will be scanning The Horizon for our sponsor.
