    Abstract: An imaging optical system includes a set of mirrors including at least three mirrors on a beam path. Only a last mirror on the beam path has a positive optical power and all other mirrors have negative optical power. The sum of the optical powers of the mirrors is zero. An external posterior aperture stop is on the beam path between the last mirror and the image plane. A back focal length of the optical system is equal to or greater than an effective focal length of the optical system. The field of view is large, and typically at least 30-40 degrees in one plane.

    Abstract: The present invention provides a wavelength multiplexer/demultiplexer comprising a plurality of regions of optically permissive material. The plurality of regions are disposed adjacent one another in a side by side relationship in order to define a stratified body. The materials in adjacent regions have differing indexes of refraction. The stratified body has a first surface and a second surface that are positioned in a non-parallel relationship with respect to one another. The first surface is a light-receiving surface, and the second surface is a light-exiting surface.

    Abstract: A spectral encoder for producing spectrally selected images of a radiation field containing multiple spectral components. An imaging spectrograph defines a first optical path that produces from the input radiation field a spectrally dispersed image comprising multiple spectral components displaced along a dispersion direction. Spectral pass bands are encoded on the dispersed image by a programmable spatial light modulator using one or more spatial masks. The imaging spectrograph further defines a second optical path that reverses the spectral dispersion of the first path and produces a spectrally-encoded polychromatic output image containing only those spectral components encoded by the spatial mask. The first and second optical paths share a common dispersing element. A detector records at least one spatial region of the spectrally encoded output image.
