The compressive sampling spectral modulated technique is developed in order to avoid time penalty and promote throughput of spectral imaging system, and a digitalmicromirrordevice based compressive sampling multispectral imaging system is designed. In the technique based compressive sampling spectral information is sampled below Nyquistcriterion with coded aperture to reduce spectral data greatly. In the experiment, the cubic spatial/spectral data cubes of the 612 nm laser and colored striped fabric are reconstructed from 2Dimension images obtained from detector that contain spectral information using double shrinkage fast iterative algorithm. The results indicate that a digitalmicromirrordevice based compressive sampling multispectral imaging system has images with highthroughput and high resolution, can compress the spectral simultaneously, and the compression ratio can reach 31∶1.
