A fellow holography enthusiast (he's not into projection like me) has been using an lcd panel to make multi-channel hologram portraits with a red laser pointer.
To get to my point quickly, he mentioned that the lcd transmits a lot more than just 10 or 12 percent of the laser light. He estimates that about 55 percent of the laser light gets through the lcd.
The theory is that the diode lasers used in laser pointers are linearly polarized, and if you line up the polarization of the laser pointer with the polarization of the lcd (they are polarized, you know) tons more light gets through than ordinarily would.
I know that red laser pointers and green laser pointers are available, does anyone know if blue laser diode pointers are available yet?
Wouldn't it be incredible to have a DIY laser projector?
I've heard somewhere about blue laser diodes being used, but I can't remember where. Anybody know?
