| description | The present invention discloses a dual-mode laser imaging system and an imaging method. The system includes a laser light source, an optical splitter, a laser processing module. a laser beam splitting module, a local oscillator switch, an echo signal receiving module, a detector, a frequency-mixing module, and a signal processing module. According to the invention, the dual-mode laser imaging system can be switched between a direct detection mode and a coherent detection mode by means of the local oscillator switch when detecting targets and laser radars are in different modes. In this way, the advantages of fast close-range imaging speed, high resolution, simple implementation and the like are realized. Meanwhile, the high-sensitivity detection of a target distance at a long distance is realized based on coherent detection. During the actual application process, the long-range single-point action distance information as far as possible and the short-range target multi-point distance information are acquired |
