An optical phased array includes a first multitude of optical transmitting/receiving elements (elements) positioned along a periphery of a first circular path. The phased array may further include a second multitude of optical elements positioned along a periphery of a second circular path concentric with the first circular path, and a third multitude of optical elements positioned along a periphery of a third circular path concentric with the first and second circular paths. The second circular path has a radius that is longer than the radius of the first circular path but shorter than the radius of the third circular. The number of the second multitude of optical elements is greater than the number of the first multitude of optical elements by N elements, and the number of the third multitude of optical elements is greater than the number of the second multitude of optical elements by M elements.
