Suppression of sun interference in the star sensor baffling stray light by total internal reflection

Abstract: We have developed a star sensor as an experimental device onboard the SERVIS-1 satellite launched in October 2003. The in-orbit data have verified its fundamental performance. One of the advantages of our star sensor is that the baffle has a small length of 120 mm instead of 182 mm in the conventional two-stage baffle design. The key concepts for light shielding are total internal reflection phenomena inside a nearly half sphere (NHS) lens and scattering light control by gloss black paint. However, undesirable… Show more

“…All of their baffle attenuation measurements were at least an order of magnitude above this level. Kawano et al [12] also used an enclosed clean room environment for their stray light testing. To alleviate surface scattering within their experiment, they erected a light trap internally coated with a specular black surface to direct rays entering the field of view into a dark cavity.…”

“…The design of internal and external stray light suppression structures, such as baffles, is based on the structural characteristics of the optical system, and the placement of the structure increases the volume and mass of the space optical payload [11]. Therefore, an optical system with a good stray light elimination capability is the focus of achieving lightweight miniaturization and improving imaging quality.…”
