Paper Abstract

Sensors detecting angle of incoming light incidence, are basic elements of systems indicating direction to source of emission and Laser Warning Systems (LWS). Onboard satellites, sensors of such type are used to determine sun position. Another sensors are used in military systems. Current method of arrival angle estimations mostly rely on the analysis of slit projection on photosensitive array or quadrant detector. Novel solution in this paper is proposed. It is based on five detectors distributed on side walls of truncated pyramid. Such geometrical configuration of detectors allows to measure in wide field of view with good accuracy offered by a small size of active surface. The proposed algorithm is able to calculate angle of both azimuth and elevation of incoming light. Laboratory tests have also been discussed in the paper.
