2-D Scanning Lidar With Mems Mirror And Stm32

In this paper, the 2-D scanning rangefinding LiDAR based on MEMS mirror and STM32 is proposed, in terms of time-of-flight(TOF) measurement, employing a APD as photodetector in order to steer nanosecond pulsed beam. The aim, centimeter-level measurement accuracy with low power consumption and a scanning angle of $+/-30<^>\circ$, were achieved using application-specific integrated circuits, optical system, TDC-GP21 chip and MEMS mirror. Compared to the traditional system, the volume of this model is much smaller. The basic function of the scanning system of receiver optics is already checked experimentally.
