Abstract: A dual-band refractive inverse telephoto lens system configured for mid-wave infrared (MWIR) and long-wave infrared (LWIR) operation. In certain examples the dual-band refractive inverse telephoto lens system includes first, second, third, and fourth lenses, each constructed from a material that is optically transparent in the mid-wave infrared and long-wave infrared spectral bands, and has an external pupil coincident with an aperture stop of the refractive inverse telephoto lens system, the aperture stop being located between the first, second, third, and fourth lenses and the infrared imaging detector to allow for 100% cold shielding.

Abstract: An all-reflective coronagraph optical system for continuously imaging a wide field of view. The optical system can comprise a fore-optics assembly comprising a plurality of mirrors that reflect light rays, about a wide field of view centered around the Sun, to an aft-optics assembly that reflects the light rays to an image sensor. A fold mirror, having an aperture, is optically supported between the fore-optics assembly and the aft-optics assembly. The aperture defines an angular subtense (e.g., 1.0 degree) sized larger than the angular subtense of the Sun. The aperture facilitates passage of a direct solar image and a solar thermal load. A thermal control subsystem comprises a shroud radiatively coupled to each fore-optics mirror and the fold mirror. A cold radiator is thermally coupled to each shroud. Heaters adjacent fore optics mirrors and the fold mirror control temperature to provide a steady state optical system to minimize wavefront error.

Abstract: A multi-channel double-pass imaging spectrometer based on a reimaging or relayed all-reflective optical form, such as a four-mirror anastigmat (4MA) or five-mirror anastigmat (5MA). In one example, such a spectrometer includes a slit through which incident electromagnetic radiation enters the spectrometer, an imaging detector positioned at an image plane of the spectrometer co-located with the slit, and double-pass all-reflective reimaging optics configured to receive the electromagnetic radiation from the slit and to output a collimated beam of the electromagnetic radiation, and further configured to produce a reimaged pupil positioned between the double-pass all-reflective reimaging optics and the image plane. The spectrometer further includes at least one dispersive element configured to spectrally disperse the infrared electromagnetic radiation in each channel and being oriented to direct the dispersed output through the double-pass all-reflective reimaging optics to the image plane.

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 LADAR system includes a transmitter configured to emit a directed optical signal. The LADAR system includes a shared optical aperture through which the directed optical signal is emitted. The shared optical aperture includes a first pupil plane. The shared optical aperture receives a return optical signal that is based on the directed optical signal. The system includes a mirror with a hole through which the directed optical signal passes. The mirror also reflects the return optical signal towards an imager. The imager receives the return optical signal and generates an image. The image is based on a portion of the return optical signal. The system also includes a partial aperture obscuration at a second pupil plane. The partial aperture obscuration may block a portion of internal backscatter in the return optical signal. The system also includes a focal plane to record the image.
