Abstract:
1. A spectral characteristic acquisition apparatus, comprising: a light emitting part configured to emit light onto an object; a light dividing part configured to divide the light reflected from the object into a plurality of light beams by a plurality of aperture parts of the light dividing part; a dispersing part configured to form a plurality of diffraction images corresponding to the plurality of aperture parts by spectrally dispersing the light beams; a light receiving part including an array of spectral sensors that receive the diffraction images and convert the received diffraction images into electrical signals; a movement part configured to move the light receiving part relative to the dispersing part in a direction parallel to a light receiving surface of the light receiving part, so that the spectral sensors receive the diffraction images at a substantially same position on respective light receiving surfaces; and an operation part configured to compute a spectral characteristic of the object based on the electrical signals.
