Electronic Shutter Testers

R. F. Redemske

The following paper, reprinted from Electronics, describes a photoelectric system which feeds a bank of stylii producing on Teledeltos paper a recording of camera shutter-opening area plotted against time, for testing both iris and focalplane shutters. Direct-indicating accessory shows per cent deviation from rated shutter speed. — The editors of the Journal feel that the methods and equipment outlined here will be of timely interest to members in the motion picture industry and allied fields.
