Description

technical field

[0001] The invention relates to the field of optical system detection, in particular to a large-diameter optical system detection method, device, equipment and storage medium. Background technique

[0002] With the higher-resolution observation requirements put forward by applications such as astronomical exploration and earth remote sensing, the research on ultra-large aperture, ultra-high-precision advanced optical systems has also been gradually upgraded. The angular resolution of an optical system is proportional to the caliber, and the development of a large-aperture optical system is limited by the difficulty of processing large-aperture optical components, and secondly, it depends on high-precision detection methods and detection equipment, and the cost is high.

[0003] At present, the imaging performance test of a large aperture optical system needs to use a collimator with an aperture equal to or larger than the primary mirror of the system to be te...
