1. An optical system comprising:
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; and
an optical filter optically coupled to the focal plane array, wherein the optical filter has a plurality of super-pixels, wherein each of the plurality of super-pixels includes a predetermined number of sub-pixels, each of the predetermined number of sub-pixels being characterized by one of a plurality of oscillatory optical transmission profiles varying in amplitude between zero and one as a function of wavelength.
