Abstract

The present application discloses a large aperture optical system detection method, device, equipment and storage medium. The method includes: designing a rectangular aperture collimator with a rectangular primary mirror; performing self-collimation calibration on the rectangular aperture collimator; controlling the calibration The final rectangular aperture collimator rotates at multiple angles to perform full-field coverage imaging performance testing in different directions of the inspected optical system; integrate the imaging performance inspection data of all fields of view of the inspected optical system to obtain the overall imaging of the inspected optical system performance evaluation results. This application detects the imaging performance of a large-aperture optical system through multi-angle rotation of a rectangular aperture collimator, which is low in cost and high in performance. High-precision testing of aperture optical systems.

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...
