ABSTRACT:
This invention relates to synchronizing switching systems for modulation of light spectrum frequencies, and a cathode-ray tube apparatus for exposing and simultaneously at electronic speed synchronizing such frequencies onto celluloid light sensitive photographic film. A method for so synchronizing modulating light spectrum frequencies, and for exposing such frequencies on such light sensitive film using a cathode-ray tube light source is related.
