    How to Cancel Ambient Light for LIDAR Receivers

    Click image to enlarge

    Figure 1: Example of different laser outputs

    ­LIDAR works by using a laser to send out a narrow pulse of light, which hits a target, and the light reflects back. A detector measures the time the reflection takes to return. By knowing the speed of light and round trip time of the laser pulse, the distance can be calculated. Generally, the higher the amplitude of
