Abstract:

Some new instrumentation was developed and a number of refinements were made in the existing special test equipment for investigating the visual recovery following high intensity flashes. The primary areas of apparatus modification were 1 increased capability for the measurement of source energy in absolute units, 2 increased precision in the measurement of recovery times, 3 extended range of flash durations for recovery measurements, and 4 inclusion of pupillographic recording as a measure of flash effect. The consensual pupil reflex was measured for six subjects for flash energies from 150,000 to 30,000,000 td.sec. The flash durations were varied from 250 microsec to 1.5 sec. Flash fields subtended a visual angle of 7.5 degrees in most of the work with a 2 degree centrally fixated field used in one part of the study.
