摘要： Aspects of the present disclosure describe systems, methods, and structures—including LiDAR—that employ multiple detectors that may determine multiple incident angles of multiple received radiation beams and advantageously do not require or employ phase shifters in illustrative embodiments and may instead—employ optical Fourier transform structures.

摘要： Aspects of the present disclosure describe systems, methods, and structures for optical phased array calibration that advantageously may be performed as a single-pass measurement of phase offset with respect to only a single interference measurement. In sharp contrast to the prior art—systems, methods, and structures according to aspects of the present disclosure advantageously produce phase offsets and phase functions of each element without time-consuming iterative procedures or multiple detector signals as required by the prior art.
