THE PHOTOMETRIC EVALUATION OF FLASHING LIGHT SOURCES IN RELATION TO THEIR CONSPICUITY.
Abstract
Different aspects of conspicuity when signals are operated under practical conditions are considered and a review is given of previous work relevant to the study of flashing lights. The present study is chiefly concerned with the variation of the threshold across the central retina, the influence of field size and flash duration upon this threshold and the fixed light equivalent of flashing lights. A three-beam optical system allowing such investigations is described. (Author)
