1. An apparatus, comprising: an emitter array of one-dimensional planar beam forming and steering optical phased array photonic integrated circuit chips in a first vertical dimension, each photonic integrated circuit chip emitting optical phase controlled unmodulated pulses of coherent light waves that interfere with each other to form an optical beam pointed in a plurality of directions in a second dimension perpendicular to the first vertical dimension; and a receiver array to collect reflected pulses indicative of the distance and the reflectivity of a sensed object, the distance of the sensed object establishing a third dimension.
