Title:
METHOD OF CALIBRATING SPECTROSCOPIC APPARATUS, AND METHOD OF PRODUCING CALIBRATED SPECTROSCOPIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/018142
Kind Code:
A1
Abstract:
In the present invention, the spectral sensitivities of sensors included in a spectroscopic apparatus are properly determined with high accuracy. The spectroscopic apparatus is provided with sensors that output signals representing the amounts of energy of a plurality of wavelength components. With respect to each of the plurality of sensors, a reference spectral sensitivity of the sensor is determined, an indicator of the reference spectral sensitivity of the sensor is determined, and the difference of an indicator of the spectral sensitivity of the sensor from the indicator of the reference spectral sensitivity of the sensor is expressed by a linear function of an indicator of a mechanical error of the spectroscopic apparatus. The indicator of the mechanical error of the spectroscopic apparatus is determined such that a collection of the spectral sensitivities of the sensors match a collection of the signals outputted by the sensors. With respect to each of the plurality of sensors, the difference of the indicator of the spectral sensitivity of the sensor from the indicator of the reference spectral sensitivity of the sensor is determined, and the spectral sensitivity of the sensor is determined.
