• Typically, when we want to take images, we use an image sensor paired with some sort of lens assembly to make a picture that’s sharply in focus. • However, [okooptics] is here to show us there’s another way-using Scotch tape in place of a typical lens element. • If you just put Scotch tape over an image sensor without a lens, you’ll just get a blurry image, whatever you point it at. • With the right algorithms, though, it’s possible to recover an image from that mess, using special “lensless imaging” techniques. • In particular, [okooptics] shows how to recreate the so-called coded aperture techniques which were previously demonstrated in [Laura Waller]‘sDiffuserCam paper. • It’s complicated stuff, but the video does a great job of breaking down the optics into understandable chunks.
