RGB holography

I will not describe how to make a hologram because I am extremely lazy and I want to somehow get round to blogging. If you don’t know, read up. That’s what I am currently doing.

I have not yet managed to get my hands on any proper holography books so I am either completely wrong in what I am about to say or someone has done it before.

Set up three lazers, one red, one green, one blue along with mirrors so that they all reach the object from the same direction. Create three seperate transmission holograms, one for each lazer. Stitch the developed film together and play it back in a loop like a film movie. Open and close the correct lazer shutters in sinc with the ‘movie’ and persistence of vision should combine the r,g and b holograms into a full colour hologram.
