Abstract

A controller corrects a spectrum S (λ) detected at a wavelength λ of signal light to S′ (λ) in accordance with expressions below: I(λ)=(I2−I1)×(λ−λ1)/(λ2−λ1)−I1, and S′(λ)=S(λ)−I(λ), where I1 is the intensity of infrared light detected at a wavelength λ1 of reference light and I2 is the intensity of infrared light detected at a wavelength λ2 of correction light.
