Abstract
At least one beam of an optical wave is transmitted along a transmission angle toward a target location from a send aperture of a transmitter. A collected optical wave is received at receive apertures of two or more receivers. Each receiver comprises: a receive aperture arranged in proximity to at least one of the send aperture or a receive aperture of a different receiver, an optical phased array within the receive aperture, which receives at least a portion of a collected optical wave arriving at the receive aperture along a respective collection angle, and a detector that provides a signal based on the received portion of the collected optical wave. An estimated distance associated with the collected optical wave is determined based on a combination that includes a respective component corresponding to each of two or more of the signals provided from the detectors of the two or more receivers.
