Re: Colour mixing in mechanical television
 

Well done Steve! Looking good.

Here, I've been improving my stereoscopic colour apparatus. A shutter rotating at half frame speed is used to switch left-right-left-right etc. This is now working about as well as I can get it.

However I wonder if a horizontal mirror screw like yours would provide a better solution, enabling 'parallel' stereo without the left-right flicker...?

Anyway, I look forward to following your further progress.

How about polarized filters, with two LED banks, and polarlized glasses?

Yes, that's a good idea! Though I expect some correcting optics would be required to ensure the stereo scanning beams won't point out radially from the screw, but will converge on the subject.

Just as I thought I'd got on top of this at last, and achieved what I'd wanted, it's beginning to look like I'm not going to get a rest after all... ;D

Next stop - to make a couple of mirror screws. One for the stereo camera, one for the monitor. Taking into account the angles etc., what would you say is the maximum practicable line count for a mirror screw?

Peter Yanczer has made a 120 line mirror screw. The more lines, the more difficult it is to align the screw. You should talk to him about it. His email is pyanczer@sbcglobal.net.
