- Abstract
- Line source electroluminescent (EL) diodes of the silicon carbide type record pulse-width modulating timing-code signals on 16mm motion-picture films at frame rates from 2 to 500 frames/s, and at pulse rates from 10 to 10,000/s. A capability of recording up to 1500 frames/s is indicated. The diodes are operated in a timing block designed for the Milliken DBM-3, 4 or 5 camera with maximum frame rate of 500 frames/s, Type EF color film (ASA 160) being used for maximum frame rate tests. Recording slit dimensions are 0.075 in by less than 0.010 in. Diode and timing block considerations are presented. Also discussed are multichannel diodes to record digital data “words” across the sound record channel width and expanded digital data records along the length of the film.
