Abstract
Described herein are systems and methods for improving detection of multi-return light signals, and more particularly to the mitigation of optical crosstalk in a Light Detection And Ranging (LIDAR) system. The methods may include cycling a passive state, where the LIDAR system receives returns from other optical sources, and in an active state, where the LIDAR system receives returns from its laser firing and from the other optical sources. By comparing the returns from the passive state and active state, crosstalk from the other optical sources may be removed. Other methods may include (1) phase locking intra LIDAR systems to fire their laser in different directions from one another; and (2) when two inter LIDAR system are firing a laser beam at one another within a field of view threshold, each inter LIDAR system may ignore the signal return from the other inter LIDAR system.
