    Abstract: A stacked-filter image-sensor spectrometer includes an image sensor, a first color filter array, and a second color filter array. The image sensor has a pixel array including a plurality of pixels. The first color filter array has a plurality of first color filters, wherein each first color filter is located above at least one pixel. The second color filter array is located between the first color filter array and the image sensor and has a plurality of second color filters. Each second color filter is located above at least one pixel. Each of the plurality of pixels has thereabove a compound color filter formed of one of the second color filters and one of the first color filters, the second filter having a second passband that partially overlaps a first passband of the first color filter in a first overlapping wavelength range.

    Abstract: Spectral imaging sensors and methods are disclosed. One spectral imaging sensor includes a light source, an array of coded apertures, one or more optical elements, and a photodetector. The light source is configured to emit a plurality of pulses of light toward an object to be imaged. The array of coded apertures is positioned to spatially modulate light received from the object to be imaged. The optical elements are configured to redirect light from the array of coded apertures. The photodetector is positioned to receive light from the one or more optical elements. The photodetector comprise a plurality of light sensing elements. The plurality of light sensing elements are operable to sense the light from the one or more optical elements in a plurality of time periods. The plurality of time periods have a same frequency as the plurality of pulses of light.
