Problems solved by technology
The structure for optical axis coupling correction has appeared, but it is problematic to only consider the optical axis coupling correction when coupling the beam - ignoring the "pupil translation", it is easy to block the beam, resulting in a decrease in the transmitted energy
The existing pupil position detection technology has very limited conditions of use and can only be realized in a small range

Description
technical field [0001] The invention relates to a light beam coupling structure suitable for precision photoelectric systems on various moving platforms such as vehicle, ship, and airborne. Specifically, it is an optical path coupling structure that can realize beam transmission between different platforms. Background technique [0002] Beam coupling technology is an unavoidable problem in the field of beam control. Among them, the beam coupling transmission between different platforms is the most common. For a static system, the beam coupling between different platforms relies on optical calibration to achieve high-precision coupling; for a system on a moving platform, the assembly relationship of the beams between different platforms in a static state will follow the movement of the moving platform. Changes occur, such as relative translational movement between different platforms or tilting or collapsing of one platform relative to another. Relying on a static assembly...
