Abstract
A plurality of one-dimensional planar beam forming and steering optical phased array chips form a two-dimensional-scanning solid-state lidar, enabling manufacturing of three-dimensional mapping time-of-flight lidars at high yield and low cost resulting from the simplicity of said one-dimensional optical phased array chips.

-
an emitter array of photonic integrated circuit chips in a first 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; 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. - View Dependent Claims (12, 13, 14, 15, 16)
