Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 8:
9. An optical measurement method comprising:
measuring irradiation of a reference sample to obtain a first detection result provided from a spectroscopic detector as a result of irradiation of the reference sample with light from a light source at first time, the reference sample being configured to maintain characteristics against variation in temperature;
measuring irradiation of the reference sample to obtain a second detection result provided from the spectroscopic detector as a result of irradiation of the reference sample with light from the light source at second time;
measuring irradiation of a sample to obtain a third detection result provided from the spectroscopic detector as a result of irradiation of the sample with light from the light source at third time temporally proximate to the second time; and
calculating a measurement value of the sample from the third detection result by performing correction processing based on change between the first detection result and the second detection result,
wherein a length of time between the first detection result and the second detection result is substantially larger than a length of time between the second detection result and the third detection result.
