Abstract

For lidar receivers, spatial filtration problems with separate recording of the multiply backscattered flux incident at different angles relative to the optical axis of the receiving lens are considered. Beam separation is performed with spatial filters selecting image fragments within the lidar receiver field of view, which greatly exceeds the transmitted beam divergence. Various instrumental realizations of spatial filter-separators are examined, such as multielement photodetectors with concentric rings, multifiber and refractive separators, and changeable diaphragms. Possibilities and peculiarities of simultaneous and sequential recording of image fragments are considered.
