ABSTRACT:
Apparatus for detecting and determining the direction of arrival of optical radiation. The apparatus includes a first mask having one or more slit apertures, a binary encoding mask which combines the functions of angle sensing and digitizing using a so-called gray encoding scheme, and interdigitated detector(s) to produce differential electrical signals, and output processing electronics for providing a digital code or word corresponding to the angle-of-arrival of the incident radiation.
