A Differential Photosensor for Indoor Optical Wireless Positioning

Ahmed Arafa, Xian Jin and Richard Klukas

Abstract: Position estimation in an indoor environment is investigated using a differential photosensor structure. Optical transmitters are mounted at fixed locations in a room while the photosensor structure, acting as the receiver, detects light from each transmitter to estimate angle of arrival (AOA) and triangulate its own position. An RMS error of approximately 2-3 cm is achieved in the 2D plane.
