Patent ID: 8368002

Claim:
A photosensitive apparatus comprising: a full width array of photosensors; and, a first photosensor chip comprising: a linear array of photosensors comprising a plurality of pixels arranged in a long direction; and, a linear variable filter adapted to transmit at least ten unique bandwidths of wavelengths of light along a length of said linear variable filter, said linear variable filter fixedly secured to said linear array, wherein each respective pixel receives a unique bandwidth of wavelengths of light as a light passes through said linear variable filter and said length is aligned with said long direction, a second photosensor chip comprising: a linear array of photosensors comprising a plurality of pixels arranged in a long direction; and, a linear variable filter adapted to transmit at least ten unique bandwidths of wavelengths of light along a length of said linear variable filter, said linear variable filter fixedly secured to said linear array, wherein each respective pixel receives a unique bandwidth of wavelengths of light as a light passes through said linear variable filter and said length is aligned with said long direction, wherein said full width array of photosensors is arranged perpendicular to a process direction of a printing device, wherein said first photosensor chip is arranged perpendicular relative to said full width array.
