Kerr Cell Method of Recording Sound
TWO types of sound recording on film are in general use, defined according to the sound track produced as variable area-constant density and constant area-variable density. The first type of record is produced by any of the methods employing vibrating mirrors or shutter arrangements. The second type of recording is done by various arrangements falling under two general classifications: (a) pulsating light source, and (b) valve action. Examples of a pulsating light source are the glow lamp of Seibt,1 the Poulson arc,2 and the mercury arc.3 Examples of those coming under the class of valves are the string galvanometer, the double grating, and the Kerr cell.
