Abstract: This application discloses a frequency modulated continuous wave LiDAR and an autonomous driving device. The LiDAR includes a light source module, a silicon photonic chip and a refraction module, and the silicon photonic chip includes a light splitting module, a coupling module and multiple transceiving units. The light splitting module receives a laser beam coupled into the silicon photonic chip, divides the laser beam into multiple beams of detection light, and transmits the multiple beams of detection light to corresponding multiple transceiving units, and the transceiving units emit the received detection light outward. The refraction module is configured to refract the detection light emitted by the multiple transceiving units to emit multiple beams of detection light in a staggered manner in a second direction, where the second direction is a direction perpendicular to the terminal surface of the transceiving unit.

Abstract: Embodiments of the disclosure provide a LiDAR assembly. The LiDAR assembly includes a central LiDAR device configured to detect an object at or beyond a first predetermined distance from the LiDAR system and an even number of multiple auxiliary LiDAR devices configured to detect an object at or within a second predetermined distance from the LiDAR system. The LiDAR assembly also includes a mounting apparatus configured to mount the central and auxiliary LiDAR devices. Each of the central and auxiliary LiDAR devices is mounted to the mounting apparatus via a mounting surface. A first mounting surface between the central LiDAR device and the mounting apparatus has an angle with a second mounting surface between one of the auxiliary LiDAR devices and the mounting apparatus.

Abstract: Provided are a pulse laser ranging system and method employing a time domain waveform matching technique. The system comprises a software part and a hardware part. The hardware part comprises an optical collimation system, an FPGA, a filter, a photoelectric conversion system, an analog amplifier circuit, a laser transmitter, a signal combination system, an ADC sampling system and a narrow pulse laser transmitting circuit. When transmitting a control signal to control laser transmission, the FPGA sends a time reference pulse to the signal combination system. The signal combination system integrates the time reference pulse with a fixed amplitude analog echo signal to form an echo signal with a time reference. The echo signal with a time reference is quantified into a digital detection signal in the ADC sampling system. The digital detection signal is sent to the FPGA to undergo data analysis. The software part is used to perform time domain waveform matching analysis to obtain a ranging result. The ranging result is output by the FPGA.
