Abstract: Scanning an opaque subject or photographic transparency with a moving spot of light found application in the early days of television. A modern version, using a short-persistence cathode-ray tube as the light source, can produce television pictures of excellent quality. Equipment restricted to pickup of transparencies can be of simple and reliable design. A motor-driven slide-changing mechanism accommodating as many as twenty-five 2- by 2-inch glass slides is described. Esthetic transitions possible include automatic picture fading preceding and following the slide change as well as unblanked changes to give the effect of instantaneous change-over. Artistic effects, particularly adapted to the flying-spot device, extend its flexibility.
