An apparatus for optical spectrometry utilizes a simplified construction, reducing the number of independent optical elements needed while providing a sizeable dispersed spectrum. The apparatus provides a spectral intensity distribution of an input source wherein individual spectral components in the source can be measured and, in some embodiments, can be manipulated or filtered.

An athermalized delay line having two optical paths whose difference in optical path length is thermally insensitive. Each optical path typically includes a reflecting quarterwave plate, each path being fed by the output from a polarizing beamsplitter. The delay line is suitable for incorporation into a PMD compensator having at least one compensation stage formed from a polarization controller and an athermalized delay line.

In the subject three-axis pointing system, the elevation and tip mirror axes are permanently mounted with their rotation axes orthogonal to each other to eliminate gimbal lock over the hemisphere, to avoid high accelerations as the zenith or nadir pointing directions are approached, and to provide optimal two-axis beam pointing control.

A multi field of view (FOV) imaging system is disclosed. In one embodiment, a dual FOV imaging system includes a composite lens array including a first lens set positioned to focus a first type of FOV and a second lens set positioned to focus a second type of FOV and a composite focal plane array (FPA) including multiple focal plane arrays (FPAs). Further, the composite FPA is disposed at the first type of FOV and the second type of FOV for producing a seamless mosaic dual FOV image of a target region.

Techniques and structures are disclosed to facilitate efficient replacement of windows/domes of optical systems, such as turreted pointer/tracker systems and seekers and other such gimbal-based or fixed targeting systems. The techniques can be implemented, for example, in a mounting ring or bezel, wherein the dome/window center of curvature is actively aligned during assembly to a reference feature on a mounting bezel during the dome-to-bezel alignment. This reference feature then mechanically registers the dome-bezel assembly to a given chassis. In some embodiments, the techniques allow for positioning of a replacement window/dome on an optical lens system, such that co-boresight of multiple beam paths is automatically maintained.
