SPECTRAL SENSITIVITY CHARACTERISTIC MEASURING INSTRUMENT AND METHOD OF MEASURING SPECTRAL SENSITIVITY CHARACTERISTIC

摘要

PROBLEM TO BE SOLVED: To provide a spectral sensitivity characteristic measuring instrument for accurately measuring the spectral sensitivity characteristic of an optical characteristic measuring instrument and a method of measuring a spectral sensitivity characteristic.;SOLUTION: A beam of light emitted from a white light source 11 passes through a sharp-cut filter 12 to turn to beams of light (hereinafter called sharp-cut beams of light) wavelength-biased by the sharp-cut filter 12. Each of the sharp-cut beams is measured by a reference spectrophotometer 13 or an object measuring instrument 14 of a spectral sensitivity characteristic measuring object to calculate the spectral sensitivity characteristic of the measuring instrument 14 by a system controller 15. The system controller 15 includes a memory for storing acquired measurement values and a calculator for calculating the sensitivity characteristics of the measuring instrument 14.;COPYRIGHT: (C)2012,JPO&INPIT
