<P>PROBLEM TO BE SOLVED: To provide a spectral characteristic acquisition device capable of obtaining spectral characteristics of plural positions with appropriate spatial resolution according to a measuring object. <P>SOLUTION: In a spectral characteristic acquisition device, an opening array having plural openings divides reflectance of light applied from light application means 11 to an image carrier medium 90 into plural regions, spectroscopic means 15 forms plural diffraction images corresponding to the plural openings, light-receiving means 16 receives the plural diffraction images at plural pixels to convert to an electrical signal, and arithmetic means 17 operates spectral characteristics indicating light volume proportion of reflectance in plural location of the image carrier medium. The arithmetic means includes transformation matrix storage means 17a for storing transformation matrix for calculating spectral characteristics corresponding to an electrical signal of a pieces (a represents a natural number equal to or larger than 2) of neighboring diffraction images; and the spectral characteristic calculation means 17b for calculating, from the electrical signal of the a pieces of neighboring diffraction images and the corresponding transformation matrix, the spectral characteristics of the a pieces of neighboring diffraction images at a location of the image carrier medium corresponding to the opening. <P>COPYRIGHT: (C)2013,JPO&INPIT |
