    Abstract: Methods and systems that compensate for the lateral chromatic dispersion and lateral shifts induced by the propagation through a switching/routing optical system. Utilizing the methods and systems of the present invention, an output of a switching/routing optical system that produces angularly dispersed output beams is achromatized by, first, deviating the output optical beam to a direction sufficient to induce lateral chromatic aberration of the opposite sign to that produced by the switching/routing optical system; and, then, re-deviating the deviated output optical beam to a predetermined direction, where a path length of the deviated output optical beam is a length sufficient to substantially compensate the chromatic dispersion induced by the switching/routing optical system.

    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.
