Re: Little old Lady

Nice work with the photopolymer, I found it more difficult to use it for RGB work than Agx. In my experience, the reconstruction of volume Agx color holograms using RGB laser light is not difficult but the angle of illumination is likely to be different from the recording angle due to emulsion shrin...

Basically I need the Q-Switch, the two etalons and the rod and pumping-chamber (I have the mirrors). I believe this oscillator is i...

Greetings, Could anyone confirm the type of Phenidone that is to be used in SM-6 developer, is it type A or B (Methyl-Phenidone) as the more sources I check the less I know... there seems to be a lot of discrepencies out there on the exact formulaes. Unless both are ok to use? Same question stands f...

Re: Geola polymer

Nice work, can you detail a bit the recording conditions?
Thx

Re: Ruby LASER for holography

Sounds awsome, are you going to post pics and details about the laser? I'd love to see it.
