    However,. You'll soon realize it's only going to transmit one big fat pixel of completely scrambled rays of the image at the light pipe objective end. I know you know about fiber bundles. You get fiber pixels, each fed from an image ray, but still scrambled, only less scrambled. Each pixel is correctly lit and colored. But translates to the wrong spot. So that bundle has to be built with the bundled fibers in perfect alignment. But then it won't flex. So you can fuse just the ends of the bundles then cut and polish them, and insert the thing into a protective flexible hose. Interestingly, because of the physical characteristics of molten glass, if you pulled a softened bundle, you would keep the pixel organization, but get higher resolution, since the bundle gets thinner. But it's also stretching longer, so you can cut it into multiple bundles an regain the original objective surface area. (with some loss due to cutting and polishing ends again). I've wanted to try to create a fiber coupled high resolution digital imager by printing a space transformer to align bundles in this jig, such that the imager end of an optical camera front end can be paved with an array of bundles, but the output end of each bundle illuminates the for of its own imaging CCD device. It would have to be an assembly that mounts onto a PCB with an array of CCD imaging devices, probably in contact with the die, otherwise it would be out of focus. Alternatively using a lens to focus the bundle image on each die. A hack to get a 16 8Mpix imagers looking at a piece of one image, for drone recon, or an astro-cam for a telescope.

    10:21 "That's fun. We're having fun! We're learning things! We're learning things on kayaks with lasers!" It's got to be said - Destin's enthusiasm and joy at figuring out, testing and playing with the world and all the amazing things in it is truly infectious. The sheer _delight,_ almost *_bursting_* out of him as he watches a laser reflect off the surface of some water, or illuminating the little globe as it hit the meniscus, can pry and dig its way through the prickliest bad mood and soon enough, you're entranced as well. I know exactly what's happening - I remember all of this stuff from High School Physics and saw much drier versions of these demonstrations back then. Seeing it performed by a guy who's exploding with happiness that he gets to see this stuff, and overjoyed that he gets to share it with other people makes the whole exercise a *_LOT_* more fun however. I'm so glad I found this channel. 13:41 "So, I hope you enjoy this half as much as I do . . ." Destin. Dude. You enjoy all of this stuff enough for *_everyone._*

    Thanks so much for the beautiful demonstration. I would love to know the details behind that interference pattern you got when shining the laser through the acrylic block. IDEA: could you build a visual analog to antenna tuning using lasers and acrylic? I know it’s not exactly the same, but the end result is similar (EM waves) and maybe there’s a way such an analog could translate into better understanding of the dark art of antenna design. ALSO another idea: I wonder if the light pipe analog can translate into an analysis of acoustic waves traveling through water pipes?

    Nice video! I learned about snells law and refraction while learning ultrasonic testing (NDT). The sound path through a transducer travels through certain materials and bounces just like the light. It’s easy to calculate the size and depth of flaws/anomalies in materials such as steel. Request: I would like to see a ultrasonic or phased array NDT video, almost everything we deal with on a daily basis goes through some sort non-destructive testing at some point. People minds will spin if you get into eddy current!

    Destin does an excellent job showing how the principles of fiber optics work in an intuitive way. Some of the earliest experiments that led to what we know as fiber optics today began by observing how light was contained in the streams of illuminated water fountains in the late 1800s. As for transmitting an image using fiber optics, the technology has actually been around since the 1950s. They are called "image guides" are used in the medical industry (endoscopes), the military, and some other industrial applications.

    Really cool video man! I have two comments about reflection and angles, feel free to skip if you aren't interested in the technicalities, or do know them. 4:55 So when we talk about angles in optics, we calculate the angle from the normal with respect to the optical boundary, ie, the surface of the lake, or the glass. So, the angle is not under the angle of incidence, but over the critical angle. The angle made by the light beam wrt the normal is called the angle of incidence. 11:27 the beam shouldn't get lighter and lighter as you point the beam up more. When you are pointing the beam up more and more, you are actually decreasing the angle of incidence (wrt normal). Now, at all angles greater than the critical angle, all light reflects, so there shouldn't be a change in the intensity as you keep tilting the laser, until after the angle of incidence, when light starts coming out. Even then, a portion of the light is reflected into the lake, it's just too faint to notice. Thus technically, the light coming out of the lake will increase in intensity as you point the beam more upwards; but this happens only after passing the critical angle.
