Paper Abstract

As the core component of lidar, APD detector is used to realize photoelectric conversion of laser echo signal. The detector needs to work at a stable temperature to ensure its application performance. A high gain amplifier circuit is designed. The temperature signal is collected by the MCU and the semiconductor refrigerator is controlled. The precision control of the temperature is realized through the PID algorithm. The adjustable high voltage module is integrated, and the APD bias voltage and temperature can be controlled through the serial port of the MCU. Reducing the volume of the APD detector, ensuring the wide temperature range of the detector and improving the integration degree of the lidar.
