The invention belongs to the related technical field of laser radar, and discloses a fiber-optic array reflective laser radar. The laser radar includes a laser, an optical fiber circulator, a transmitting optical part, an optical fiber array, a coupling lens, a rotating mirror and a control module. The left end face of the optical fiber array is located on the focal plane of the emitting optics, the right end end face is located on the focal plane of the coupling lens, and the optical fiber array is provided with a central optical fiber; the rotating reflector and the optical fiber The arrays are respectively located on opposite sides of the coupling lens; the control modules are respectively connected to the rotating mirror and the laser, and are used to control the rotation of the rotating mirror to be synchronized with the laser emission of the laser; The fiber circulator is formed with three ports, and two of the three ports are respectively connected to the central fiber and the laser. The lidar reduces costs, has a small volume, and has better concealment.
Description
technical field [0001] The invention belongs to the related technical field of laser radar, and more specifically relates to a laser radar of optical fiber array reflective type. Background technique [0002] Lidar is an active modern optical remote sensing technology, which is the product of the combination of traditional radar and laser. Because laser has the characteristics of high brightness, high directionality, high monochromaticity and high coherence, LiDAR has the advantages of high resolution, high measurement accuracy, strong anti-interference ability, and can obtain various images of the target. It is used in environmental monitoring, marine monitoring, forest survey, topographic mapping, deep space exploration, military applications, etc. In recent years, the application of lidar to unmanned driving is also quite popular. [0003] Laser radar technology is to emit laser light to the target, and then receive the laser echo signal reflected by the target. After s...
