Fabricated MTF filter array for single-shot computational spectroscopy. (a) Photograph (left) and optical microscope image (right) of the fabricated MTF filter array. (b) Examples of spectral sensitivities of MTF filters with the CMOS camera. (c) Examples of measured data include a monochrome image of the MTF filter array (left), some extracted intensities from monochrome images (center), and the GT spectra of incident lights corresponding to the extracted intensities (right).
