Abstract
A sparse optical phased array transmitter/receiver includes, in part, a multitude of transmitting/receiving elements that are sparsely positioned. Accordingly, the transmitting/receiving elements are not uniformly distributed at equal distance intervals along a one-dimensional, two-dimensional, or a three-dimensional array. The positions of the transmitting/receiving elements may or may not conform to an ordered pattern.
