A Projector Type Light Flux Generator for Testing Light Sensitive Devices
E.B. Kurtz, Jr Potter · Proceedings of the IRE · 1933
A novel light flux generator is described which is capable of giving a sinusoidal light flux for frequencies up to 100,000 cycles or higher per second, for use in the testing of television equipment or other equipment using photo-electric cells. An experimental and calculated curve is shown to verify the accuracy of the apparatus.
