A high frame-rate compressive spectral video system is developed. The 4-dimensional targets (space, time and spectra) are captured by multi-spectral LED modulated illumination. The reflection of targets passing through an objective lens is modulated by a digital micro-mirror device (DMD) in the spatial domain, which is then collected by a RGB sensor through an imaging lens. The rapidly changing LED illumination patterns and DMD codings provide unique modulations for each temporal frame. Mathematical modeling and simulation are shown all as well as experimental results.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
