1. A spectral filter, comprising:

  • a photosensitive array having a plurality of photosensitive elements, at least a subsection of photosensitive elements of said array along one direction thereof being configured such that each element of said subsection along said one direction receives light of a different wavelength range of a characteristic spectrum and produces an electrical signal corresponding thereto, said subsection being configured to combine signals of at least two photosensitive elements and to output said combined signal as a measure of the optical energy within a bandwidth of interest of said characteristic spectrum.
