Title
(EN) Laser radar and transmitting module, receiving module and detection method thereof
(ZH) 激光雷达及其发射模组、接收模组、探测方法
Abstract
(EN) The invention discloses a laser radar and a transmitting module, a receiving module and a detection method thereof, the transmitting module of the laser radar comprises a plurality of lasers, the light emitting wavelengths of the lasers comprise a first wavelength and a second wavelength, and the lasers suitable for emitting light at the same time have different light emitting wavelengths; the receiving module of the laser radar comprises a plurality of detectors, and each detector is suitable for receiving an echo light beam, reflected by a target object, of a laser beam emitted by a corresponding laser in an emission module. By adopting the scheme, the anti-interference capability among a plurality of detectors can be improved, and the signal receiving performance of the laser radar canbe effectively guaranteed.
(ZH) 激光雷达及其发射模组、接收模组、探测方法,所述激光雷达的发射模组包括:多个激光器,所述激光器的发光波长包括第一波长和第二波长,适于同时发光的激光器具备不同的发光波长;所述激光雷达的接收模组的包括:多个探测器,每个探测器适于接收发射模组中对应的激光器发出的激光光束被目标物反射的回波光束。采用上述方案,能够提高多个探测器之间的抗干扰能力,有效保障激光雷达的信号接收性能。
