Wow! A physics forum! Here's the device I filed a U.S. patent for, so I'm wondering what to do next? http://www.youtube.com/watch?v=wYgfRzxc-Hs I've talked to the chair of my physics department and he said the amount of light arriving at each pixel is very small. CCDs are becoming very efficient, so this could become viable in the next 20 years. There's also the possibility that the source image is presented via a 2D laser array. This has some properties of a 2D collimator, but also some properties of a pinhole light field mask. I've shown this presentation to a bunch of people in industry, but they aren't helpful, so I must try a different method. Should I submit a paper? Write a conference poster? Any other ideas? Thanks!
