Abstract
An Anderson localized hyperspectral filter array is disclosed which includes a base layer and a plurality of optical layers deposited on the base layer selected from two or more materials, each material having a refractive index that is different from the other materials of the two or more materials, wherein no consecutively deposited optical layers have the same refractive index, each of the plurality of optical layers having a thickness chosen based on a random number within a predetermined range.
