Abstract

The invention relates to a monitoring device based on optical axis refraction, comprising a detector component, a first reflection component, a second sleeve, and a refraction component. The connection between the first reflection component and the second sleeve is provided with a first driven motor The first gear transmission assembly, the connection between the catadioptric assembly and the second sleeve is provided with a second gear transmission assembly driven by the second motor; the catadioptric assembly is provided with a rotatable and swinging prism assembly; the detector assembly and the first reflector The components are connected and the position can be adjusted, and the detector component can realize the replacement and position adjustment of the camera, laser and light source; the optical axis generated by the detector component is adjusted by the reflection of the first reflection component, the reflection adjustment of the second sleeve, The rotational refraction adjustment and the yaw refraction adjustment cooperate with each other to realize the three-level precision adjustment of the optical axis. Compared with the prior art, the present invention can realize 360° wide-range optical axis adjustment and sub-micro-radian precise optical axis pointing, and can simultaneously realize imaging, tracking and lighting of monitoring objects.

Description

technical field [0001] The invention relates to the technical field of photoelectric tracking, in particular to a monitoring device based on optical axis refraction. Background technique [0002] With the advent of the era of artificial intelligence, scene monitoring technology has been widely used in security monitoring, traffic management, ground search and rescue, military reconnaissance and other fields. 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. [0003] Prior art (application number: CN201610934565.6, application date: "Laser Coarse-fine Coupling Scanning Method by Steering Double" on November 1, 2016 and Anhu Li, etc., "Laser Coarse-fine Cou...
