Abstract
Within a Fabry-Perot filter apparatus, a method for fabricating the Fabry-Perot filter apparatus and a method for operating the Fabry-Perot filter apparatus, there is employed a Fabry-Perot filter and at least one color filter layer, both assembled over a substrate and covering at least two optical transducer elements which are formed within the substrate. Within the foregoing apparatus and methods, the at least one color filter layer comprises at least two color filter elements of separate color, each registered with a separate optical transducer element within the at least two optical transducer elements. The apparatus and methods provide for enhanced optical discrimination properties.
