This paper presents an in-situ beamforming method for optical phased array LiDAR systems, leveraging an on-chip photodetector to perform real-time phase error corrections. This system achieved a wide 53.6° scanning range with a side mode suppression ratio of 10 dB and a divergence angle of 0.38° in the 128-channels optical phased array.
