Abstract
A range of devices used in predetector processing of a backscattered radiation flux in the laser receiving system is considered. These include a variety of spatial filters improving the signal-to-noise ratio and compressing the dynamic range by a controlled vignetting of backscattered radiation and special masks and rasters, including those for separating multiply scattered signals. Different configurations of polarization analyzers are proposed to determine the Stokes parameters in lidar returns.
