Abstract
In a biological component measurement device according to the present disclosure, a modulation unit intensity-modulates excitation light emitted from an excitation light source and the intensity-modulated excitation light is incident to an optical medium. The modulation unit switches a plurality of modulation frequencies in order from a low frequency to a high frequency. The plurality of modulation frequencies include a first frequency and a second frequency higher than the first frequency. A light position detector detects a position of probe light when the sample is irradiated with excitation light intensity-modulated at the first frequency and a position of probe light when the sample is irradiated with excitation light intensity-modulated at the second frequency. The biological component acquisition unit measures a biological component of the sample based on the position of the probe light at the first frequency and the position of the probe light at the second frequency.
