Problems solved by technology

The problem with this solution is that laser detection can only work in the 360° circular detection mode, and it is difficult to achieve staring detection of targets within a certain field of view; in addition, limited by the emission frequency of the laser, 360° circular detection is difficult. Obtaining high-resolution laser detection data is difficult for some special tasks

Abstract

The invention discloses a laser active imaging detection system. The laser active imaging detection system comprises a driving motor, a first decelerating mechanism, a multi-line laser receiving module, a second decelerating mechanism, a reflector and a multi-line laser transmitting module. A laser active imaging detection method disclosed by the invention comprises the following processes: the multi-line laser transmitting module transmits multi-line laser to be irradiated onto the reflector, the reflected light is irradiated onto a detection target and reflected back, the laser reflected bythe reflector is always parallel to the optical axis of the multi-line laser receiving module, the multi-line laser receiving module receives the reflected laser, and the driving motor drives the first decelerating mechanism, the multi-line laser receiving module, the second decelerating mechanism and the reflector to rotate, thereby realizing detection on different positions of the target and completing high-speed and high-definition detection on the target in a specific field angle range.

Description

technical field [0001] The invention relates to the technical field of laser imaging, in particular to a laser active imaging detection system and method. Background technique [0002] Laser imaging uses a laser beam to scan an object, reflects the reflected beam back, and obtains an image in a different arrangement sequence, and uses the image gap to reflect the formed image. Laser imaging has the ability to detect beyond the line of sight and can be used for satellite laser scanning imaging. In the future, it will be used in remote sensing mapping, laser analytical ionization imaging technology, laser scanning display and other scientific and technological fields. [0003] At present, the laser active imaging detection system mainly adopts the following scheme: the multi-line laser emitting module and the multi-line laser receiving module are fixed on the rotating platform at the same time, and the driving motor drives the rotating platform to rotate to realize 360° scanni...
