A single-pixel camera composed of optical coding masks, a photo detector, and a decoding computation has an important feature of no image sensor for imaging, therefore it has very simple optical and electrical architectures. The optical coding masks whose implementation is a novelty of our research are composed of holes on a substrate, and arranged on the circumference of a disk enables us to switch with a rotation of the disk. The main features are small wavelength dependence other than air for wideband spectral imaging, and the simple structure. The spectral imaging for a sample composed of three color films is demonstrated, and the accuracy of the proposed system is evaluated.
