Coded Aperture Snapshot Spectral Imagers (CASSI)
Coded Aperture Snapshot Spectral Imagers are computational sensors that are able to recover a 3D datacube representing spatial and spectral information at every pixel in an image of a scene using just one snapshot 2D projection. The imagers rely on aperture coding and compressed sensing theory to achieve snapshot spectral imaging.

Computational Spectral Microscopy
Computational Spectral Microscopy We have extended the use of high throughput spectrometers to spectral microscopy applications. A pushbroom scanned high-throughput spectrometer on the back-end of a microscope creates a three dimensional cube (2D spatial, 1D spectral) from a fluorescent fixed-cellular assay. Current system designs include a snapshot dual disperser (DD-CASSI) architecture. Our goal includes imaging dynamic cellular events using fluorescence microscopy as a tool. The benefits of these computational spectral imagers applied to microscopy include high throughput analysis and a higher spectral measurement when compared to conventional spectral imaging systems.
