Abstract

A method of measuring the total illuminance of the diffracted image of an incoherent line source is described. Measurements on a 6-in. focal length objective are reported. Experimental measurements of this kind give a quantitative measure of lens system performance in terms of total illuminance of the diffracted image of a line source. The results of theoretical diffraction calculations based upon lens design data were compared with experimental values and showed good correlation.
