The invention relates to a system and a method for pulse wave LIDAR. In some embodiments, a light detection and ranging (LIDAR) system includes a laser source configured to provide an optical signal at a first signal power; an amplifier having a plurality of gain levels, the amplifier configured to amplify the optical signal at the plurality of gain levels; and one or more processors. The one or more processors are configured to vary a gain level of the amplifier according to a plurality of gain levels based on a first signal power and a duty cycle of the optical signal to generate a pulse signal, transmit the pulse signal from the amplifier to an environment, receive a reflected signal reflected from an object in response to transmitting the pulse signal, and transmit the reflected signal to the amplifier. And determine a distance to the object based on an electrical signal associated with the reflected signal.
本发明涉及用于脉冲波LIDAR的系统和方法。在一些实施方式中,光检测和测距(LIDAR)系统包括激光源,其被配置成以第一信号功率提供光信号;放大器,其具有多个增益级别,该放大器被配置成以多个增益级别放大光信号;以及一个或多个处理器。一个或多个处理器被配置成基于光信号的第一信号功率和占空比来根据多个增益级别改变放大器的增益级别,以生成脉冲信号,将脉冲信号从放大器发射到环境,响应于发射脉冲信号,接收从对象反射的反射信号,并且基于与反射信号相关联的电信号来确定到对象的距离。
