The invention relates to a large-scale optical axis coarse and fine adjustment device, which includes a detector assembly, a first reflection assembly, a sleeve two, and a catadioptric assembly arranged in sequence; the detector assembly is connected to the first reflection assembly and its position can be adjusted to detect The sensor assembly can realize the replacement and position adjustment of the camera, laser and light source; the catadioptric assembly is equipped with a swing mirror assembly, and the swing mirror assembly is rotated by the yaw mechanism controlled by the motor three; the optical axis generated by the detector assembly passes through the first The reflection adjustment of the reflection assembly, the reflection adjustment of the second sleeve, and the yaw refraction adjustment of the catadioptric assembly cooperate with each other to realize the secondary precision adjustment of the optical axis. Compared with the prior art, the optical axis of the present invention is adjusted through the reflection of the reflective component and the adjustment of the deflection and refraction of the prism, which can realize the two-level coarse and fine adjustment of the optical axis, and at the same time realize the 360° wide-range optical axis adjustment and submicro-arc precision The optical axis is pointed, and has the advantages of simple structure, low cost and convenient operation.
Description
technical field [0001] The invention relates to the technical field of photoelectric tracking, in particular to a large-range optical axis rough 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 attracted extensive attention from domestic and foreign experts, scholars, 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. However, in traditional photoelectric tracking monitoring systems, large-scale optical axis adjustment and high-precision pointing are a pair of conflicting indicators, which restricts monitoring. further development of technology. Contents of the invention [0003] The object of the present invention is to provide a large-range optical axis rough and fine adjustment device in ord...
