Total internal reflection solar coronagraph sensor and thermal control subsystem

摘要

Coronagraph optical systems and methods for continuously imaging a wide field of view, including the sun, are provided. Examples of coronagraph optics are a fully reflective front optics assembly that receives light rays from the observed scene and a direct sun image of the sun, and a sensor assembly configured to generate an image of the observed scene. Between the fully reflective relay optics assembly, which is configured to receive the rays from the front optics assembly and reflect the rays to the sensor assembly, and between the front optics assembly and the relay optics assembly. A direct solar image of the sun is reflected avoiding the relay optics assembly and the rays are reflected through the relay optics assembly while being placed and the incident aperture of the front optics assembly is continuously positioned towards the sun. Includes solar exclusion optics that can be dynamically configured to be reflected into.
