Abstract
Method and systems related to obstructing a first predefined portion of at least one defined wavelength of light incident upon a first photo-detector array; and detecting the at least one defined wavelength of light with a photo-detector in a second photo-detector array.

-5. (canceled)
A system comprising:
- a first photo-detector array permeable to at least one defined wavelength of light impinging upon said photo-detector array;
- a second photo-detector array sensitive to the at least one defined wavelength of light;
- and
- an optical filter configured to partially obstruct the at least one defined wavelength of light by a predefined amount, said optical filter located between and proximate to said first photo-detector array and said second photo-detector array.
1 more element
A system comprising:
- a set of N+1 photo-detector arrays, each pair of which is proximate to and separated by an optical filter, such that relative optical spectrums entering N of the photo-detector arrays are substantially different from each other, and such that a relative optical spectrum entering photo-detector array N+1 has a substantially similar relative spectrum as that relative spectrum entering the first photo-detector array.
