I am new to this forum as of yesterday.
I have been researching holograms for about a year now for a project I am working on and am coming unstuck on one particular area:
Transparent holographic recording medums
I am basically trying to find out about holograms that use HRI (high refractive index) in their replay and also Photopolymer.
I wonder if there are any experts on this forums who could offer some advice/answers re when these types first came about and exactly what it is that separates these types from traditional reflection / transmission holograms etc?
Is there anyone out there who can help or point me to some information or person who possibly could??
