THE APPLICATION OF PHOTOGRAPHIC PHOTOMETRY TO ELECTRONIC DISPLAY SYSTEMS.

Abstract

A technique for determining absolute luminance of objects as viewed by an orbiting Tiros satellite is described. Because the Tiros system was designed to provide qualitative rather than quantitative photographic data on meteorological conditions, cloud formations, geographic location of storm centers, etc., it was necessary to perform an analysis of the discontinuities and nonuniformities in the photoelectronic portion of the system which distorted the luminance display. The assignment of luminance values to the viewed object, as imaged ultimately in photographic film, involves the alteration of object luminances by (1) the satellite-borne, opticalelectronic imaging system, (2) the conversion of illuminance to telemetered signal, (3) the transmittal of this information to a ground receiving station, (4) the ground monitor cathoderay tube (CRT), and the photographic recording and development processes. Each of the factors altering the luminance transfer were quantitatively evaluated to allow the determination by the satellite system of cloud luminance. (Author)
