Patent ID: 8294100

Claim:
An apparatus comprising: a plurality of pixels each configured to detect radiation incident thereon, the plurality of pixels configured to detect at least two different wavelength ranges of a short wavelength infrared spectrum, the plurality of pixels comprising: a first pixel configured to detect a first range of wavelengths in the short wavelength infrared (SWIR) spectrum and produce a first photoresponse indicative of a quantity of radiation in the first range incident thereon; and a second pixel configured to detect a second range of wavelengths in the SWIR spectrum and produce a second photoresponse indicative of a quantity of radiation in the second range incident thereon, the second range differing from the first range; and readout circuitry configured to read out the first and second photoresponses, wherein the first pixel comprises a first photodetector and the second pixel comprises a second photodetector, and wherein each of the first and second photodetectors is capable of detecting a third range of wavelengths in the SWIR spectrum, the third range of wavelengths comprising the first range and the second range.
