The invention relates to a large-range optical axis coarse and fine adjustment device which comprises a detector assembly, a first reflection assembly, a second sleeve and a catadioptric assembly which are arranged in sequence. The detector assembly is connected with the first reflection assembly and is adjustable in position, and the detector assembly can realize replacement and position adjustment of the camera, the laser and the light source; a swing mirror assembly is arranged in the catadioptric assembly and rotates through a deflection mechanism controlled by a third motor. The optical axis generated by the detector assembly achieves secondary precision adjustment of the optical axis through mutual cooperation of reflection adjustment of the first reflection assembly, reflection adjustment of the second sleeve and deflection refraction adjustment of the catadioptric assembly. Compared with the prior art, through reflection adjustment of the reflection assembly and deflection refraction adjustment of the prism, secondary coarse and fine adjustment of the optical axis can be achieved, meanwhile, 360-degree large-range optical axis adjustment and sub-micro-radian accurate optical axis pointing are achieved, and thedevice has the advantages of being simple in structure, low in cost and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of photoelectric tracking, in particular to a large-scale optical axis coarse and fine adjustment device. Background technique [0002] With the advent of the era of artificial intelligence, scene monitoring technology, as one of the key technologies, has received extensive attention from domestic and foreign experts and scholars, scientific research institutes, and high-end technology companies. Large-scale optical axis adjustment and high-precision optical axis pointing have always been the beautiful vision pursued by monitoring technology, but in the traditional photoelectric tracking monitoring system, large-scale optical axis adjustment and high-precision pointing are a pair of conflicting indicators, restricting monitoring. further development of technology. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a wide-range optical axis coarse and fine adjustment devic...
