A frame rate of 10 fps is experimentally achieved using thermo-optic phase shifters, with a theoretical upper limit of 62 fps.engSilicon Photonic FMCW LiDAR with Integrated High-Speed Line-Scan Illumination and 2D Coherent ReceiversProceedings paper10.1109/ecoc66593.2025.11263059WOS:001680185000137
