Paper Abstract

This survey is principally concerned with the measurement of glare in the visible spectrum for complete optical instruments. It covers the traditional black aperture methods, originated by Goldberg in 1922, and proceeds to the more powerful elementary-source technique which leads to the concept of the glare spread function (GSF). Various national standards for glare are then listed, all of which are based upon the traditional "black-spot" method. It is then shown that the GSF can be directly related to the loss of image contrast and it is suggested that test methods based upon glare spread functions would be more satisfactory than the techniques incorporated in the existing national standards.
