| abstract | PROBLEM TO BE SOLVED: To provide an optical characteristic measuring apparatus and method capable of performing measurement in an environment with large fluctuations and temperature changes regardless of the type of measurement object, having a wide measurement frequency range and high measurement accuracy. . An optical characteristic measuring apparatus includes a nonlinear optical crystal that generates a photon pair A and B and emits the photon A to an optical element 4, and an optical delay circuit that changes an optical path difference between the photon A and the photon B. 6 and photons A and B are transmitted and reflected, and the reflection component of photon A and the transmission component of photon B are mixed and guided to photon detector 7A, and the transmission component of photon A and the reflection component of photon B are mixed The beam splitter 5 that leads to the photon detector 7B, the coincidence device 8 that measures the frequency at which photons are simultaneously detected by the photon detectors 7A and 7B as a coincidence rate, and the optical path difference from the measured coincidence rate. And an analyzer 9 that calculates a change in the coincidence rate with respect to the change and calculates the wavelength dependence of the optical characteristic value of the optical element 4 based on the value of the dip portion in the change in the coincidence rate.
