Abstract:

The spectral reflectance of an object can show the color of an object from its intrinsic properties. As a result, it is very important to reconstruct the spectral reflectance of the object. In this paper, a method of spectral reflectance reconstruction based oncompressive sensing by gradual modulation wheel is proposed. A light source modulated by a grating and a gradual modulation wheel is irradiated onto an object, and the spectral reflectance is received by a single pixel detector. Different experimental devices are set up for color block and multispectral image. The spectral reflectance of the multispectral image is further modulated by a spatial modulator, and then the multispectral image is received by a single pixel detector. In the simulation experiment, the effect of different cycle transformation on the gradual modulation wheel is investigated and the objective evaluations are structural similarity, peak signal to noise ratio and root mean square error, which has allowed to determine exact conditions for the best spectral reflectance reconstruction and the accurate copying of the multispectral image.
