Patent ID: 7224468

Claim:
An apparatus for medical imaging or manufacturing process control using multiple wavelength detection, said apparatus comprising: a light source operable to produce light at different wavelengths, said light directed at a sample under test; and an imager operable for detecting light from said sample under test, said imager comprising a plurality of first regions, said plurality of first regions comprising a filter material for detecting light that comprises light at a first wavelength while blocking light that comprises light at a second wavelength, said imager further comprising a plurality of second regions, said plurality of second regions comprising a filter material for detecting light comprising light at said second wavelength, wherein said first and second regions each corresponds to a respective pixel of said imager and wherein said first regions and said second regions are interleaved in a pattern, and wherein a signal value corresponding to said second wavelength is determined for a first region using signal values from a subset of said second regions neighboring said first region.
