Digital Inline Holography with a Laser Pointer
I hadn’t heard of inline holography before, but apparently it was proposed decades ago by a short article in Nature by Gabor.  Basically it is a technique by which interference patterns between an object and a reference wavefront is recorded, and then reconstructed in using clever math and the FFT.  Very neat. Laser Pointer Holography
