Abstract

We discuss the design of a Digital Micromirror Device-based Snapshot Spectral Imaging (DMD-SSI) system for NIR wavelengths. A pair of low/high dispersion glasses was selected for building an NIR relay-lens and a double-Amici prism, which are needed for generating Compressive Sensing (CS) measurements in experimental settings. Aberrations of the system were simulated using the Zemax software, which were considered in a numerical model of the system. CS measurements were generated using this model accounting for those aberrations. We evaluated the quality of the spatial/spectral data-cubes reconstructed using those non-ideal CS measurements and discuss possible solutions of enhancing the reconstruction quality.
