Single-photon laser radar active and passive imaging detection system

The invention discloses a single-photon laser radar active and passive imaging detection system which comprises a laser emission subsystem, a laser receiving subsystem and a sequential control and data processing subsystem. The laser emission subsystem is used for realizing pulse laser emission and outputting a light-emitting synchronizing signal at the same time; the time sequence control and data processing subsystem is used for receiving the light emitting synchronizing signal output by the laser emission subsystem, outputting a trigger signal to the laser receiving subsystem and processing detection data output by the laser receiving subsystem; the laser receiving subsystem receives signals according to a preset frequency or based on trigger signals output by the time sequence control and data processing subsystem; the single-photon laser radar active and passive imaging detection system performs imaging detection in a passive working mode or an active and passive cooperative working mode.
