Dark Adaptation of Rated Air Force Officers Using Electroluminescent versus Incandescent Light Sources

摘要

An experimental study was conducted to determine the effects of electroluminescent versus incandescent light sources on the dark adaptation of rated Air Force officers. The parameters of dark adaptation that were tested are (1) absolute luminance threshold of vision; (2) resolution of visual detail as provided by square wave spatial frequency gratings; and (3) comfort level of cockpit lighting as determined by rated Air Force personnel. Results show that (1) electroluminescent and incandescent light sources have the same effect on the absolute luminance threshold and the resolution of visual detail; and (2) significant differences exist between the two light sources in the comfort level of cockpit lighting as chosen by the subjects.
