Abstract
The microdensitometer is extensively used in studying a variety of problems of sound-film recording and reproducing: in studying the operating characteristics of light-modulating devices; in plotting variations of light transmission of sound-tracks in respect to the harmonic content of film records; in establishing correct operating technic in film processing; in studying the photographic characteristics of film as regards its ability to record high frequencies; and many other aspects of sound recording and reproducing. The commercially available microdensitometers are not well suited to making such studies unless proper means are taken to assure correct comparisons with data obtained with a calibrated reproducer. The present paper describes the modifications of a Moll microdensitometer that have converted it into a satisfactory instrument for sound-picture investigations.
