Abstract

For applications such as remote sensing and bio-imaging, images from multiple bands can provide much richer information compared to a single band. However, most multispectral imaging systems have difficulty in acquiring images for high-speed moving objects. In this paper, we use a DMD-based temporal compressive imaging (TCI) system to obtain high-speed images of moving objects over a broad dual-band spectral range, in the visible and the near-infrared (NIR) bands simultaneously. To deal with the degraded reconstruction caused by the optics, four nonuniform calibration strategies are studied, which can also be implemented into other compressive imaging systems. Moving objects covered by paint or through a diffuser are reconstructed to demonstrate the superior performance of the calibrated broad dual-band TCI system.
