Abstract

Near infrared (NIR) optical wireless communication provides a promising solution for point-to-point indoor high speed wireless data link. To cover a large area and several multiple users, wavelength-encoded laser beam steering has been demonstrated in previous research work. One remaining challenge in beam steered optical wireless system is real-time user localization. In this paper, ultrafast complete user localization at update rate of 10 MHz based on instantaneous optical wavelength detection and chirped pulse correlation has been demonstrated. Both angular position and absolute distance of each user have been accurately detected.
