    You may want to use a first surface mirror if you're not already doing so. I used to make machine vision applications and if the camera angle needed to be changed. Using a regular mirror would result in the primary image from the reflective surface on the back of the glass, and a second ghost image reflected from the front of the glass.

  • @Spirit532

    Fun fact: all of these wacky lenses simulated in this video actually exist, and are widely used in manufacturing and inspection! Telecentric(no perspective) lenses are most common and very popular in metrology, but pericentric(seeing more than one side of the object), hypercentric(seeing behind and/or underneath the object), and even wacky combinations with mirrors. This allows you, as a common example, to inspect the cap on a plastic bottle from all sides, at the same time, using the same camera. Above, around the corners, from the side, AND from below!

    Using two cameras seems unnecessarily redundant-it mainly acts as a counterweight to balance the setup (via centripetal force) while slightly speeding up the imaging process.
    Also, are we really being told that moving a camera around an object lets you see more of it? Shocking revelation…

Printed threads are stronger than cut threads with both resin types and fdm types (with the caveat that it depends on how you print the part. Obviously a 20% or cheap resin won't be able to compete).

    It's an an absolutely incredible device, and takes a large chunk of brilliance. Eliminating perspective is so cool and it's a key feature of a Synthetic Apeture Radar. That said, the creation process is not teaching the viewers a good methodology for creating a complicated system. I don't know if you did it off camera, but instead of trying to eat the elephant in one bite, show stepping up from simple prototypes first to make a proof of concept work for each element of the system. It would avoid a lot of the nearly impossible debugging of the full scale complicated system simultaneously with 100s or 1000s of possible interacting sources of error.

    Applied Science did something similar a few years ago using huge fresnel lenses. The video is called "Hypercentric optics: A camera lens that can see behind objects".

    I applaud your tenacity. I don't know how you manage to do it every time instead of giving up before succeeding in the end.

    @StuffMadeHere I thought for sure you were going to try and scatter a laser or something to try and bounce around objects. Then somehow read it. Isnt what you did kinda just the same as if someone just walked to the left or right until they could see you behind the wall? Still amazing and I love your vids. Just think this one is kinda cheating. More looking behind than seeing behind the wall. :)

    The last photo process is literally digital cubism which is really cool!

    You can shorten the exposure by using multible arms and let them expose different sections of the image.

    You are an inspiration to many young engineers to try and make things on their own and experiment and test. Its wonderful.

    There actually are cameras that see around corners. They measure the time it takes photons to bounce off a wall, hit the object, off the wall again, and then hit the detector. Then with tons of math you can get the general shape of an object that’s occluded. The Smithsonian Magazine has an article about it from 2012 if anyone is interested.

      I was going to bring this up - it's an interesting ability that emerged out of the research methodology referred to as "femtophotography".

    This is epic. I wonder what would happen if you added thermal imaging or radar cameras, would you be able to see partially through blocked areas if they were in the middle? Or even use the data they give for better alignment of the final coloured image?

    Seeing the effort you put into spinning the camera balanced really makes you appreciate the engineering of a CT scanning machine.
