| 摘要 |
In a spectral imaging apparatus which is provided with a variable wavelength spectroscopic element transmitting light so that transmitted light is light with a plurality of peak wavelengths in predetermined wavelength ranges and changing a distance between surfaces of a pair of optical substrates opposite to each other to change the peak wavelengths, the spectral imaging apparatus includes a light splitting unit which splits light transmitted by the variable wavelength spectroscopic element into components in each of the predetermined wavelength ranges and image-capturing units each of which captures only a spectral image formed by the components in each of the wavelength ranges into which the light transmitted by the variable wavelength spectroscopic element is split by the light splitting unit, the wavelength ranges including the peak wavelengths respectively, and the image-capturing units capture images respectively and simultaneously. |
