Simulation of External Stray Light for FY-3C VIRR Combined with Satellite Orbit Attitude Model
Remote Sensing, 2021 Optical imaging systems mounted on a Sun-synchronous satellite are probably disturbed by stray light when working in the space environment. Existing research has shown that the Visible Infrared Radiometer (VIRR) onboard the FY-3C satellite is affected by

Stray-Light Suppression of the Internally Occulted Reflecting Solar Corona Imager
Frontiers in Physics, 2022 In order to achieve a clear observation of the ultra-low brightness solar corona and provide a physical basis for forecasting space weather that seriously affects the human living environment, the stray-light suppression level becomes the key factor ...

A physically based correction for stray light in Brewer spectrophotometer data analysis [PDF]
Atmospheric Measurement Techniques, 2023 Brewer ozone spectrophotometers have become an integral part of the global ground-based ozone monitoring network collecting data since the early 1980s. The double-monochromator Brewer version (MkIII) was introduced in 1992. With the Brewer hardware being

NuSTAR spectral analysis beyond 79 keV with stray light [PDF]
, 2022 Due to the structure of the NuSTAR telescope, photons at a large off axis (>1°) can reach the detectors directly (stray light), without passing through the instrument optics.

Stray Light Suppression of Wide-Field Surveillance in Complicated Situations
IEEE Access, 2023 Wide field and long exposure time can effectively improve the ability of space surveillance telescope to detect weak space targets. However, this is easily affected by stray light, resulting in the effective target submerged in the background of stray ...
