Abstract:
Wavelength information indicating a correspondence relationship between a plurality of light receiving elements of a light receiving unit and wavelengths of pieces of lights is stored. First and second intensity distributions of the light related to first and second dispersion images are acquired based on a signal outputted from each of the light receiving elements when a monochromatic light is passed through a opening of a light shielding body and first and second dispersion images related to primary and secondary diffracted light are formed on the light receiving unit. An estimated intensity distribution of the light related to the second dispersion image is calculated from the first intensity distribution according to a predetermined relational expression. A change amount related to the wavelength information is calculated based on the estimated intensity distribution and the second intensity distribution. The wavelength information is corrected according to the change amount.
