The compact 3-D imaging ladar system was established, which uses high PRF laser pulses and a C30659-1060-R8B avalanche photo-diode (APD) detectors with independent digital time-of-flight counting circuits. The scanner uses galvanometer-oscillating mirror. Range resolution is 35 cm and scanner angle is 0~±25°. Scan frequency is: 20 Hz for±25°,50 Hz for±10°. With appropriate optics, the digital time value represents a 3-D spatial image frame of the scene. Successive image frames illuminated with the multi-kilohertz pulse repetition-rate laser are accumulated into range histograms to provide 3-D volume and intensity information.
