The color TV cameras used on the Apollo lunar missions used a rotating color wheel.

For the “C” panel, it needs a warning, “Do not use telescope-like device with remaining eye!”

On the receiving end, the 3 chip DLP video projectors must use dichroic mirrors/prisms to combine the images before they enter the lens.
45 kilobucks!?!

Single chip DLP units use a rotating color wheel to produce the colors in rapid succession.

The microscopic wobbling mirrors don’t wear out.
Thanks Nanotechnology!

Those dichroic mirrors were and are used in broadcast cameras up to the present day! Any three-chip camera will have dichroic prisms, same thing.

I think the guy playing with the color changing optics has reinvented LCD’s.

Was there ever a successful color TV system that worked this way?
