  • Abstract
    A differential and direction-sensitive device capable of detecting and locating intensity variations with angular resolution is presented. The device consisting of four conventional photodetectors integrated with a pair of GaAs quantum-well modulators measures intensity variations at angles of nπ/4 (n=1, 3, 5, ...) with respect to the x-direction.
