    Abstract: An imaging platform minimizes image distortion when there is relative motion of the imaging platform with respect to the scene being imaged where the imaging platform may be particularly susceptible to distortion when it is configured with a wide field of view or high angular rate of movement, or when performing long-stares at a given scene (e.g., for nighttime and low-light imaging.) Distortion correction may be performed by predicting distortion due to the relative motion of the imaging platform, determining optical transformations to prevent the distortion, dynamically adjusting the optics of the imaging platform during exposure, and performing digital image correction.

    Abstract: A movable sunshade system includes a baffle extending along a central axis of an entrance pupil of a lens and a sunshade movably connected to the baffle. The sunshade includes a first portion shaped to cover a portion of the baffle that is spaced from the first end of the baffle and a second portion that extends from the first portion. The second portion is shaped to cover a portion of a field of view (FOV) of the entrance pupil. The movable sunshade system further includes an actuator configured to move at least one of the baffle or the sunshade to selectively cover portions of the FOV of the entrance pupil.

    Abstract: All-reflective optics for use in imaging spectrometers. In one example, an imaging spectrometer includes an entrance slit and spectrometer optics consisting of a primary mirror, a secondary mirror having a diffraction grating formed thereon, and a tertiary mirror, each of the primary mirror, the secondary mirror, and the tertiary mirror having free-form non-rotationally symmetric surface figures defined by Zernike polynomials. The spectrometer optics are configured to receive the telecentric image at the entrance slit, to disperse the optical radiation into its spectral components to provide dispersed optical radiation, and to focus the dispersed optical radiation onto an image plane positioned in a common plane with the entrance slit. The spectrometer optics have a physical length that is twice the length of the entrance slit, a ratio of a distance of the secondary mirror from the entrance slit to a distance of the primary mirror from the entrance slit being approximately 0.32.
