Abstract: This paper adopts image reconstruction method based on sub-Gaussian random projection to get a computer simulation experiment result using sparse projection matrix and very sparse projection matrix as measurement matrix. It proposes a compressed imaging system based on digital micromirror device, it presents system construction, the relation of components and the technique of design for key component. In order to satisfy the system need of detecting the weak light signal of high frequency changing, it designs a detecting component for weak light signal with single detector. Experimental result proves that the scheme is rapid speed, excellent preciseness and outstanding application.
