Abstract: Hyperspectral resonant cavity imaging spectrometers and imaging systems incorporating the resonant cavity spectrometers are provided. The spectrometers include an array of photodetectors based on photosensitive semiconductor nanomembranes disposed between two dielectric spacers, each of the dielectric spacers having a thickness gradient along a lateral direction, such that the resonant cavity height differs for different photodetectors in the array.

Abstract: Micrometer-scale x-ray photodetectors that utilize a flexible array of photodiodes wrapped around the circumference of a scintillator core are provided. The photodetectors use dense and flexible pixelated arrays of photodiodes disposed around the circumference of a crystalline scintillator to provide highly compact photodetectors with high spatial, temporal, and energy resolution.
