Abstract: The present disclosure provides an optical imaging system that defines an optical path. In an aspect, the optical imaging system includes a first optical sub-system configured to substantially image, at a focus plane, electromagnetic radiation emanating from an object plane, a slit element at the focus plane to extract a line image from the electromagnetic radiation, a second optical sub-system configured to collimate, at a center plane, the electromagnetic radiation from the slit element, a dispersive element at the center plane with variable dispersive properties, a third optical sub-system configured to image the collimated electromagnetic radiation from the center plane to an image plane, and a detecting element at the image plane. In one example, the slit element is mechanically movable into and out of the optical path.

Abstract: The present disclosure provides an optical imager and a method for imaging electromagnetic radiation. In one aspect, the optical imager includes an object array substantially located at an object plane, a first catadioptric element configured to substantially collimate, at a central plane, electromagnetic radiation emanating from the object array, a second catadioptric element configured to image the substantially collimated electromagnetic radiation from the central plane onto an image plane, and a detecting element substantially located at the image plane. The first catadioptric element includes at least one refractive surface and at least one reflective surface, and the second catadioptric element includes at least one refractive surface and at least one reflective surface.
