| titleOfInvention | Optical measuring method and optical measuring apparatus |
| abstract | In an optical measurement method and an optical measurement apparatus for optically measuring a substance to be detected in a sample liquid, measurement with a high S / N ratio is possible with a low load by eliminating the influence of excitation light. In an optical measurement apparatus for measuring the presence and / or amount of a test substance A in a sample, a signal component indicating a value corresponding to the quantity of the test substance A and excitation light Le by a polarization modulation element driver 22 The excitation light Le is frequency-modulated and irradiated to the sensor unit at a low frequency where both noise components caused by the stray light are to be detected, and the light is measured in synchronization with the low frequency by the frequency analyzing unit 24 to measure the low frequency. The measurement signal is acquired, and the polarization modulation element driver 22 modulates the excitation light Le at a high frequency that is a detection target of only the noise component, and irradiates the sensor unit with light. To obtain a high frequency measurement signal, and the calculation unit 25 obtains a difference between the low frequency measurement signal and the high frequency measurement signal.
