Compressive Sampling Spectral Modulated Technique
The compressive sampling spectral modulated technique is developed in order to avoid time penalty and promote throughput of spectral imaging system, and a digitalmicromirrordevice based compressive sampling multispectral imaging system is designed. In the technique based compressive sampling spectral information is sampled below Nyquistcriterion 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 2Dimension images obtained from detector that contain spectral information using double shrinkage fast iterative algorithm. The results indicate that a digitalmicromirrordevice based compressive sampling multispectral imaging system has images with highthroughput and high resolution, can compress the spectral simultaneously, and the compression ratio can reach 31∶1.
