Abstract

The invention discloses an optical zero compensation method and system for a laser tracking and aiming device. The method comprises the steps that: the laser tracking and aiming device is adjusted, so that target light spots are located right in front of a four-quadrant detector, and the areas of the target light spots distributed in four quadrants of the four-quadrant detector are the same; after the conditions are met, a feedback control loop is opened, a servo mechanism is locked, and the laser tracking and aiming device is continuously adjusted to rotate around the center axis by 180 degrees; output signals of the four quadrants of the four-quadrant detector after 180-degree rotation are obtained, the misalignment angle of the laser tracking and aiming device is calculated and determined according to the output signals, and the servo mechanism is adjusted according to the misalignment angle. According to the method and system of the invention, the error of the laser tracking and aiming device can be compensated simply and quickly, repeated disassembly and assembly can be avoided, and manpower is saved.

Description

technical field [0001] The invention belongs to the technical field of laser testing, and more particularly relates to an optical zero compensation method and system for a laser tracking and aiming device. Background technique [0002] In the laser aiming device, the four-quadrant detector is the key "eye" of photoelectric conversion. Each quadrant of the four-quadrant detector is functionally a photodiode. Next, the photodiode will generate electrons due to the stimulated absorption process, forming a current, and the magnitude of the formed current is proportional to the magnitude of the light energy it receives. The four photodiodes of the four-quadrant detector form four quadrants I, II, III, and IV. When the light beam is incident on the photosensitive surface of the four-quadrant detector, the actual output of the four-quadrant detector is the converted voltage signal. [0003] In the aiming device, the target laser signal is focused on the detector through the optica...
