Abstract: A hyperspectral optical element for monolithic detectors is provided. In one embodiment, for example a hyperspectral optical element includes a faceplate layer adapted to be mounted on top of a monolithic detector. The faceplate layer comprises a reflective inner surface. A notched layer includes a plurality of notched surfaces and is mounted to the faceplate layer. The notched surfaces oppose the reflective inner surface of the faceplate and define a plurality of variable depth cavities between the reflective inner surface of the faceplate layer and the plurality of notched surfaces of the notched layer. The faceplate layer and the notched layer are substantially transparent to a received signal and the plurality of variable depth cavities provides resonant cavities for one or more wavelengths of the received signal.

Abstract: A multi-channel imaging device is provided. The multi-channel imaging device comprises a focal plane array comprising an array of pixels configured to detect radiation in a predetermined wavelength band. Subsets of the array of pixels are arranged to define a plurality of unit cell image areas. The multi-channel imaging device also comprises a lens array comprising a plurality of lens elements configured to image a scene onto the plurality of unit cell image areas. The lens elements and the unit cell image areas define a plurality of unit cells comprising at least one lens element and at least one unit cell image area. Each of the plurality of unit cells is configured to create a complete image of the scene. Additionally, a plurality of unit cell filters corresponding to the plurality of unit cells is configured to filter radiation such that each unit cell is dedicated to an image channel is also provided.
