Navy Electronic Shutter Analyzer

W. R. Fraser

A new electronic shutter analyzer employing a two-gun cathode-ray oscilloscope with two phototubes has been developed by the Navy. This device is designed to permit the rapid analysis and solution of numerous problems commonly encountered in photography including: (1) shutter operation and efficiency; (2) shutter-flash synchronization; (3) shutter-solenoid delay; (4) flash-gun-switch, solenoid-shutter delay; (5) internal-shutter-switch contact time; (6) switch or electrical contact efficiency; (7) diaphragm calibration; (8) duration and intensity of light as emitted by flashbulbs and some gaseous discharge tubes.
