Abstract

Implementation of hybrid scanning system in wide and narrow angle fields provide high precision positioning of the laser beam in space, fraught with difficulties. Scanning attachment for SRS - lidar system has been developed to perform automated scanning of the test area in the angular field of ± 50. The module performs automated scan of the test area in the angular field of ± 50 on 50-100 m distance. Movement of the laser beam in a spiral occurs due to rotation in one direction wedges with different speeds, which speed is in the range of 50-200 Hz. The laser beam had a divergence of 1.5 mrad. Because the spatial resolution at the outer coils falls compared with the center spiral wedges speeds ratio increases from 0.8 to 0.97, respectively.
