ABSTRACT:
A telescope design is disclosed that has at least some of its interior facing surfaces configured with corner reflectors, so that a detector operatively coupled to the telescope views itself, instead of those surfaces. The corner reflectors may be on, for example, interior facing surfaces of a conventional baffle appended to the telescope and/or mirror supports or other structures inside the telescope housing that are within the detector's FOV. Likewise, the corner reflectors may be on interior facing surfaces of a baffle that is integrated into the telescope housing. In some such cases, the integrated baffle can be configured as both a baffle and a mirror support. The integrated baffle can be shaped to the F-cone between mirrors of a given telescope design, and/or configured to minimize or otherwise reduce the total obscuration of the baffle to improve the optical throughput.
