Incoherent spatial filtering of lidar signals and its technical potentialities

摘要

Technical potentialities of incoherent spatial filters for analyzing the brightness function of a scattering volume in the lidar observation plane are discussed. Such an analysis allows one to receive additional information on the multiply scattered component of a lidar signal. To this end, incoherent spatial filters limiting the receiving flux of a scattered radiation in the receiving objective focal plane are used. It is shown, however, that the potentialities of this analysis are limited.
