ABSTRACT:
Imaging devices having reduced fixed pattern noise are disclosed. The fixed pattern noise in the imaging devices is reduced by measuring and adjusting the spectral characteristics of the imager device on a pixel by pixel basis. The fixed pattern noise of the pixel cells are changed by modifying the absorption, reflectance, refractive index, shape, and/or micro structure of the material.
