Abstract
The lidar systems may reduce stray light interference. A system may comprise a laser system which, upon receiving a signal at a first time, generates an illumination light. A polarizing beam splitter (PBS) may receive the illumination light from the laser system along a first light path and the illumination light may exit from the PBS along a second light path. A quarter wave plate (QWP) may receive the illumination light exiting from the PBS along the second light path and may pass the illumination light to an object from which the illumination light is reflected. A detector arranged proximate the PBS may receive the reflected light from the PBS along a third light path and may detect the reflected light at a second time, and a processor may determine a distance to the object based at least in part on the illumination light and the reflected light.
