[0002] Laser radar is an active remote sensing technology that uses laser as the light source and photoelectric detection technology. Compared with ordinary radar, laser radar has the advantages of high resolution, good concealment, strong anti-interference ability, good low-altitude detection performance, small size and light weight. Laser radar consists of a transmitting end, a scanning end, a receiving end and an information processing end. The laser transmitting end needs to adjust the optical path of the laser and lens components to achieve the appropriate spot size, position, emission angle and power requirements.

The first acousto-optic modulator changes the X-axis direction of the optical path; the second acousto-optic modulator changes the Y-axis direction of the optical path. The laser radar dimming device provided by the utility model has no adjustment structure, realizes remote automatic dimming, and does not require on-site operation by operation and maintenance personnel.
