Patent ID: 8415607

Claim:
An imaging system for characterizing electromagnetic energy from an object that propagates along a light path, at least a component of said electromagnetic energy carrying electromagnetic energy information along said light path, said imaging system comprising: a first detector array arranged at a first position along said light path, said first detector array including a plurality of photosensitive elements aligned to receive at least some of said electromagnetic energy, including the component, said first detector array being configured to selectively absorb a first portion of said component, and to produce therefrom a first set of electrical image data based at least in part on said electromagnetic energy information to at least partially characterize the component of the electromagnetic energy, at least some of said photosensitive elements being at least partially transparent with respect to said electromagnetic energy, to selectively pass a second portion of said component therethrough to continue along said light path; and optics for directing electromagnetic energy from said object along said light path to the first detector array; wherein said plurality of photosensitive elements includes: a first layer group of alternating layers of high refractive index material and low refractive index material, a second layer group of alternating layers of high refractive index material and low refractive index material, first and second transparent conductive layers disposed between the first and second layer groups, and a photosensitive layer disposed between the first and second transparent conductive layers, at least the photosensitive layer having a non-zero extinction coefficient.
