Abstract

A LiDAR system comprises: laser source(s) to transmit laser light having first polarization toward measurement location(s); detector(s) to receive and determine intensity of backscattered light having second polarization from measurement location(s); polarization adjustment device(s) to control first polarization and thereby second polarization of backscattered light; polarization filtering device(s) to control third polarization of light received at detector(s); and processing circuitry to: identify positions of and determine orientation of detector(s) relative to Sun; determine fourth polarization of solar light received from Sun based on orientation; determine, based on fourth polarization: desired configuration for polarization adjustment device(s) to cause first polarization and fourth polarization to approach perpendicular; and desired configuration for polarization filtering device(s) to cause third polarization to approach parallel with second polarization; and control polarization adjustment device(s) and polarization filtering device(s) to desired configurations to maximize transmission of backscattered light and minimize transmission of solar light to detector(s).
