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. The optical wave comprises at least a first portion, and a second portion having a different characteristic from a characteristic of the first portion. Two or more receivers include at least one receiver comprising: 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, the optical phased array being configured to receive at least a portion of a collected optical wave arriving at the receive aperture along a respective collection angle, and a filter configured to filter the received portion of the collected optical wave according to the characteristic of the first portion of the optical wave.
