We report on the development of a digital-micromirror-device (DMD)-based multishot snapshot spectral imaging (DMD-SSI) system as an alternative to current piezostage-based multishot coded aperture snapshot spectral imager (CASSI) systems. In this system, a DMD is used to implement compressive sensing (CS) measurement patterns for reconstructing the spatial/spectral information of an imaging sce...

Four data-driven low-order modeling approaches, Dynamic mode decomposition (DMD) and three other variations (optimal decomposition, total-least-squares DMD high-order DMD), are used to capture the spatio-temporal evolution of fluid–structure interactions. These methods applied experimental data obtained in a flow over flexible membrane wing its elastic deformation. Spectral coherence indicates ...

A digital micromirror device (DMD) has a wide range of applications in holographic display, light field manipulation, etc., due to its high-speed refresh rates. In order precisely control the wavefront, influence array structure DMD requires careful analysis. Based on an accurate three-dimensional phase model DMD, we analyzed diffraction characteristics DMD. The was established by accurately de...
