Abstract
A photosensor which is capable of detecting the direction of incidence as well as the intensity of optical radiation. The detector comprises an array of photodetector cells arranged under a diffuser dome. The direction of incidence of the optical radiation can be determined by a comparison of the voltage outputs of each of the photodetectors in the array, these outputs being directly proportional to the amount of optical radiation falling upon each photodetector in the array. The intensity of the optical radiation can be determined by an analysis of the average output of the photodetector array.
