Abstract: A method and a system for acquiring a hyperspectral image by using a kaleidoscope are provided. The method includes copying an input image to generate a specific number of images, generating coded-aperture passed images corresponding to the images by using at least one coded aperture, and acquiring a hyperspectral image for the input image based on the coded-aperture passed images.

Abstract: 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.
