Abstract
An improved optical direction of arrival sensor in which incoming radiation passes through a cylindrical lens placed through a top mask and is focused in the gap between the lens and a detector array concentric about the back of the lens. The focal line then expands and falls on the detector array which embodies an encoding scheme. The output from the encoded detector is then processed to determine the angle of incidence of the incoming radiation with the top mask.
