Abstract: An optical element is disclosed. The optical element includes a plurality of layers. The plurality of layers includes a notch filter array that has a plurality of notch filter elements. Each notch filter element is configured to filter out energy within at least one wavelength band of interest. The plurality of layers further includes a polarization-responsive grid array having a plurality of polarization elements and includes a microlens array having a plurality of microlens elements. Each microlens element is configured to image a portion of a scene onto an image plane.

Abstract: A system including a first refractive lens doublet comprising a first fixed focal length lens and a first liquid-based lens, the first liquid-based lens responsive to transition between a convex configuration and a concave configuration when electronically actuated, and a second refractive lens doublet comprising a second fixed focal length lens and a second liquid-based lens, the second liquid-based lens responsive to transition from a convex configuration to a concave configuration when electronically actuated. A focal length of the first liquid-based lens and a focal length of the second liquid-based lens are switched between a positive focal length and a negative focal length when electronically actuated to provide a net focal length to produce a varied collimated magnification of light.

Abstract: An apparatus and method for combining a plurality of laser beams to form a single output beam comprising employing a plurality of lasers and optically connecting an image rotator and recoupler to each of the plurality of lasers.

Abstract: A three mirror anastigmatic optic (and corresponding method of making) comprising a primary mirror, a secondary mirror, a tertiary mirror, and a vertex common to the primary and tertiary mirrors.
