  • All-reflective solar coronagraph sensor and thermal control subsystem
    Patent number: 10345562
    Abstract: An all-reflective coronagraph optical system for continuously imaging a wide field of view. The optical system can comprise a fore-optics assembly comprising a plurality of mirrors that reflect light rays, about a wide field of view centered around the Sun, to an aft-optics assembly that reflects the light rays to an image sensor. A fold mirror, having an aperture, is optically supported between the fore-optics assembly and the aft-optics assembly. The aperture defines an angular subtense (e.g., 1.0 degree) sized larger than the angular subtense of the Sun. The aperture facilitates passage of a direct solar image and a solar thermal load. A thermal control subsystem comprises a shroud radiatively coupled to each fore-optics mirror and the fold mirror. A cold radiator is thermally coupled to each shroud. Heaters adjacent fore optics mirrors and the fold mirror control temperature to provide a steady state optical system to minimize wavefront error.
