Abstract:
A spectrometer assembly, comprising:a substrate having thereon a plurality of optical sensors and one or more processing elements,a plurality of filter elements fixedly positioned over at least a first group of the sensors and fixedly positioned with respect to the substrate, wherein the plurality of filter elements have spectral transmission characteristics over one or more predetermined spectral bands;an optical imput unit comprising at least a randomized fiber optic bundle having at least one input comprising a plurality it of fibers and a plurality of outputs each comprising a plurality of fibers, wherein the fibers of the plurality of outputs receive light from fibers of the at least one input in a randomized pattern, wherein the plurality of outputs are fixedly positioned over at least certain of the plurality of filter elements and fixedly positioned with respect to the substrate, wherein light entering the input is transmitted to the plurality of outputs, wherein at least a portion of the light is transmitted form the outputs through at least certin of the filter elements and is sensed by at least certain of the sensors;wherein light may be coupled to the input, wherein at least first spectral data corresponding to the light is generated by the one or more processing elements, wherein the spectrometer assembly is fabricated in a fixed manner with respect to the substrate.
