Title:
SPECTROSCOPE AND SPECTROSCOPIC MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2014/033783
Kind Code:
A1
Abstract:
The problem addressed by the present invention is to measure the strength distribution of the wavelength of each color in a precise manner and by means of a simple configuration. The present invention is characterized by being provided with: 18 filter units (28) respectively having the wavelength of each of 18 colors as a transmission peak; 18 light reception elements (25) that respectively receive incoming light that has passed through the 18 filter units (28), and output a photoelectric current value; a recording unit (31) that records a correction matrix resulting from converting to an inverse matrix a coefficient matrix of transmission coefficients that are for each color and for each filter unit (28) and that are obtained by causing 18 types of calibration light having differing specific strength distributions to enter each; and a calculation unit (32) that calculates a strength distribution by means of a multiplication process between the correction matrix and each photoelectric current value of the 18 light reception elements.
