Abstract

The invention discloses an automatic stray light suppression system for an asteroid detection camera, which comprises: a camera lens barrel, a plurality of first sun sensors are uniformly installed on the outer wall of the camera lens barrel; a driving mechanism, the driving mechanism Installed on the camera lens barrel; special-shaped hood, the special-shaped hood is installed on the driving mechanism; the driving mechanism includes: double row angular contact bearing, the inner ring of the double row angular contact bearing is sleeved on the camera lens barrel ; Mounting seat, the mounting seat is installed on the outer ring at the bottom of the double row angular contact bearing, the drive assembly is installed on the mounting seat; driven gear, the driven gear is installed on the top of the double row angular contact bearing On the outer ring of the drive assembly, the driven gear is meshed with the output end of the drive assembly. The invention continuously adjusts the angle of the special-shaped shading cover according to the azimuth angle of the sun to block the stray light from the sun, and realizes automatic azimuth judgment and suppression of the stray light from the sun.

Description

technical field [0001] The invention relates to the technical field of space detection, in particular to a stray light automatic suppression system of an asteroid detection camera. Background technique [0002] In order to make more effective use of space and explore space more deeply, all major aerospace powers are actively researching space surveillance technology. Space surveillance is mainly to detect, identify and track specific space targets, mainly through ground-based observation systems and space-based observation systems. Compared with ground-based observation systems, space-based observation systems have the following significant advantages: they are not constrained by geographic location and meteorological conditions, and can observe targets from different directions; Higher signal-to-noise ratio; the space-based observation system is in orbit, and only one star is needed to cover the entire geosynchronous orbit. In view of the advantages of space-based observa...
