Abstract
An optical system includes a focal plane array having a plurality of pixels defined by a first number of pixels arrayed in a first direction and a second number of pixels arrayed in a second direction. The optical system also includes an optical filter optically coupled to the focal plane array. The optical filter has a plurality of super-pixels. Each of the plurality of super-pixels includes a predetermined number of sub-pixels and each of the predetermined number of sub-pixels is characterized by one of a plurality of oscillatory transmission profiles as a function of wavelength.

A system comprising:
- a focal plane array having a plurality of detector pixels;
- an optical filter optically coupled to the focal plane array, wherein:
- the optical filter comprises a substrate and a plurality of filter pixels;
- and
- each of the plurality of filter pixels corresponds to one of the plurality of detector pixels;
- and
- a processor;
- wherein each of the plurality of filter pixels is defined by a thin film stack height corresponding to an oscillatory optical transmission profile varying in amplitude between zero and one as a function of wavelength.
