Patent ID: 8810808

Claim:
A method comprising: providing or obtaining at least a first nanowire device comprising at least a first pixel and a second pixel, wherein the first pixel comprises a first nanowire comprising a first predetermined material and a first diameter, the first pixel configured to detect light of a first predetermined wavelength, and the second pixel comprises a second nanowire comprising a second predetermined material and a second diameter, the second pixel configured to detect light of a second predetermined wavelength; determining a first error difference between a first spectral response of the first nanowire to the light of the first predetermined wavelength and one or more standard spectral response curves; determining a second error difference between a second spectral response of the second nanowire to the light of the second predetermined wavelength and the one or more standard spectral response curves; and determining a total error difference of the first nanowire device at least from the first and second error differences; wherein at least one of the first predetermined wavelength and the second predetermined wavelength is an infrared wavelength.
