Self-correcting laser transmit-receive system

The utility model relates to a self-correcting laser transmitting-receiving system, which uses a shielding device to shield areas with different receiving apertures of a reflecting telescope to obtain echo signal characteristics, and controls a movable reflecting mirror to move relative to the reflecting telescope based on the echo signal characteristics of the areas with different receiving apertures. The direction of the laser beam emitted to the fixed reflector is adjusted by adjusting the direction of the laser beam emitted to the fixed reflector, so that the characteristics of echo signals in different areas of the receiving aperture of the reflecting telescope are isotropic, that is, the laser beam emitted by the fixed reflector basically keeps the requirement of coaxial emission relative to the optical axis of the reflector, thereby simplifying the correction process of the laser transceiver and improving the calibration precision. And the correction efficiency and accuracy are improved. 本公开涉及一种自校正激光收发
