Default Re: Colour mixing in mechanical television

PJL - You are correct. The light source needs to be 3 to 6 feet away, and the horizontal resolution is determined by the slit width. The .75 mm fibers I have chosen will result in about 170 lines of resolution, which is more than enough. The fiber optic approach will provide equal intensity from all viewing angles, and after thinking about it I have concluded that the recessed LED approach will require a ground glass (or some other object) at the slit to work. The question is which approach will provide the most illumination.
