摘要： Disclosed are a hyperspectral imaging method and an apparatus thereof. A method of reconstructing a hyperspectral image includes receiving an image photographed through a diffractive optical element and reconstructing a hyperspectral image of the received image based on the received image and information about a point spread function for each wavelength of the diffractive optical element. The diffractive optical element may generate an anisotropic shape of the point spread function that varies with a spectrum.
