ABSTRACT:
An imaging sensor has multiple fields of view of the same scene that may be selected by the user for viewing through mechanical movements. The imaging and selection are accomplished entirely with reflective optical components (mirrors) and without the use of any refractive optical components (lenses). A movable field-shifting mirror selects between a direct view and a modified-of-view image of the scene. The modified-view image is accomplished using a multi-mirror afocal telescope. Additional field-shifting mirrors may be used to select other fields of view and reference sources, as desired, or between various detectors.
