I also had a good summer, starting off with ISDH 2012, I then helped a Grad student @ SUNY Stony brook shoot a few holograms of a very cool Engineered Diffuser, eventually he wanted to run it in reverse so he could send in a diffuse beam and get a collimated beam exiting the hologram. Playing around with this neat little device spurred an idea to use this as a RGB combiner, (stay tuned on that one)! I was also asked to provide a laser for illuminating a Bruce Nauman hologram (circa 1970s),on display @ the New Museum located here in NYC. I used a red 635nm diode laser, they asked another "expert" to bring in his diode laser to try and improve the feeble image, but to no avail, mine won hands down (i think his output was 650nm)........... the max allowed mw was 30-40mw, so i tuned mine 60mw or so and then pulsed the output so it was half on/half off, they never picked up on it using an analog power meter !
Nice ED, what could be greener than Makin holograms with the sun !
