Wavelength shift correction system and wavelength shift correction method

摘要

Wavelength shift correction system and method of the present inventionA wavelength shift correction light source for emitting a wavelength shift correction light including a plurality of wavelength shift correction light beamsThe dispersion of the incident light is distributed according to wavelength.A spectrometer is provided as a wavelength shift compensation spectrometer having a spectroscopic section which receives and receives light from a plurality of photoelectric conversion elements arranged in a dispersion direction and outputs respective electrical signals corresponding to the respective light intensities of the dispersed spectral light.When the wavelength shift correction light is measured with the wavelength shift compensation spectrometer as the incident lightAmong the plurality of photoelectric conversion devicesA wavelength change amount is obtained based on the respective electric signals output from a plurality of specific photoelectric conversion elements for receiving a plurality of wavelength shift correcting light rays.At least one of the plurality of specific photoelectric converters isA plurality of the plurality of wavelength shift correcting light rays are received.
