Abstract
The stray light is one of the main factors affecting the imaging quality of optical remote sensor. The design and experimental verification of stray light suppression is also the key link in the design of aerospace optical remote sensor. This article based on the development needs of aerospace cameras in orbit, the stray light suppression analysis and product assurance of imaging remote sensing cameras with RC configuration as the optical system (or main optical system) were studied in a quantitative way. First of all, the stay light characteristics of such cameras were revealed in a quantitative way, the design and addition of the optimal stray light suppression structures were completed, and comprehensive simulation verification was carried out through the light path tracking method. Secondly, in the design stage, in strict accordance with the control requirements of the development of aerospace remote sensing camera, the necessary and reasonable product guarantee control point is set up by PDCA cycle method. Finally, through laboratory stray light qualitative tasting and on-orbit verification, the full-link verification of camera stray light suppression is completed. This paper can provide a reference for stray light suppression design and process quality control of large-caliber optical remote sensors.
