Classification: CPC G | IPC G

Claim 0:
1. An optical measurement system comprising:
a light source;
a spectroscopic detector;
a reference sample configured to maintain characteristics against variation in temperature;
a switching mechanism, including an optical switch or an optical shutter, that switches between a first optical path through which a sample to be measured is irradiated with light from the light source and light produced at the sample is guided to the spectroscopic detector and a second optical path through which the reference sample is irradiated with light from the light source and light produced at the reference sample is guided to the spectroscopic detector; and
a processor and/or hard-wired logic circuit that calculates, by performing correction processing based on change between a first detection result provided from the spectroscopic detector as a result of irradiation of the reference sample with light from the light source at first time and 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, a measurement value of the sample from 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,
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.
