AI Technical Summary
In the existing technology, the focal plane calibration process of space cameras suffers from problems such as large errors, low efficiency, and severe error coupling during multi-dimensional adjustment. In particular, it is difficult to achieve high-precision and efficient focal plane position adjustment when there is no focusing mechanism or a single-dimensional focusing mechanism.
An automated focal plane calibration device for a multi-dimensional space camera is adopted, including an angular stage, a tilting stage, and a translation stage. Through motor drive and feedback device, multi-dimensional precise adjustment of the focal plane components is achieved. High-precision measurement and feedback are performed using components such as grating rulers, digital display differential screws, and planetary gear reducers to ensure decoupling of each dimension.
It achieves high-precision adjustment of the focal plane position, improves calibration efficiency, is applicable to different types of space cameras, features automation and easy disassembly and assembly, decouples errors in various dimensions, and has wide applicability.
