Keywords:LiDAR, Beam Steering, optoelectronic device

We have developed a MEMS phased array supporting up to infrared wavelength and demonstrated ToF LiDAR. This MEMS phased array is a spatial light modulator composed of thousands of controllable independent structures over 100kHz. It is realized 3D depth mapping by 1D line beam steering with high precision in a horizontal direction and detecting a vertical direction of 1D array sensor. We showed ±3% precision into known distances of ~5.5m. We will report in detail on the performance of the beam steering by the MEMS phased array on the day.
