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.

It's been a busy week for me, wading through piles of SIGGRAPH sketch reviews, so I haven't had too much inclination to spend more time in front of a computer.Â Â But I did find this article linked on the make blog: little tips about making rc micro_helicopter.Â A very cool micro helicopter, which used a CDROM drive motor for the main drive.Â Very cool.
