hello people, i'm Ömer Gezer, 23, located in İstanbul and studying mechanical engineering in ITU. My hobbies vary to many technical fields like photography, computers, dj'ing, chemistry, electronics, mechanics etc. I've always wondered about holograms autostereoscopic capabilities but had no idea si...

Hello, i found some uv sensitive thin film photopolymer material on ebay, and ordered it for circuit board etching. i've read somewhere these photopolymers are sensitive in the 350-450nm range so the first thing i thought is, can we make blue/violet holograms on them? similiar items by other compani...

Hey Din, What you say is different from what intend to do but i think it's an easier method to record holograms of 3d models from a computer. i think a DLP chip(is actually a slm with moving pixel mirrors on it's surface) or a small lcd slm from a common video projector would work. in case of dlp ch...

okay, this may sound dumb but can we make a hologram printer with a simple 2D CNC machine modified to focus the image on an OLED screen to the small parts of a holographic recording medium one by one? let's guess we have a printing head moving across the x-y plane made of square OLED screen(or led o...

Hey lobaz, indeed you are totally correct, i'm trying to catch all those at the same time, but this is my nature, it also brings me to failure most of the time. well it's mostly because i don't want to spend a $100 on an integraf kit, i was looking for the cheapest replacement of all those items tha...

Thanks Steven! the resources you gave are very useful and just the thing i was looking for, it seems this osram pl520 green diode is somewhat usable in some ecdl mode i don't understand yet, my question for this topic is answered! the simple denisyuk setup is indeed i'll go for a long way, maybe lat...

Thank you Joe, your answer is much of help. i plan to use low power laser diodes since they are cheap and i can be sure of their stability after running in idle for like 10 mins(correct me if i'm wrong), they are also cheap. Are DPSS lasers diode lasers? i saw many of them but not sure of their coho...

hello, i want to start on hobby holography, read many materials and i've choosen the DIY way. i first want to make my own normal dichromate plates and pose them with blue/violet laser diodes(i know green laser diodes are not applicable due to their low coherent length caused by their working princip...
