摘要
A photosensitive apparatus including a full width array of photosensors and a first photosensor chip. The first photosensor chip including a linear array of photosensors having 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 the linear variable filter where the linear variable filter is fixedly secured to the linear array. Each respective pixel receives a unique bandwidth of wavelengths of light as a light passes through the linear variable filter and the length is aligned with the long direction. The full width array of photosensors is arranged perpendicular to a process direction of a printing device.
