Abstract
A living body function measurement method comprises separating a light from a low coherence light source into a signal light and a reference light, modulating a frequency of at least one of the signal light and the reference light, irradiating the signal light to an observation area of a living body sample, giving a stimulation to the living body sample from an outside of the living body sample, synthesizing the signal light via the observation area and the reference light and detecting a heterodyne interference signal, and measuring a living body function of the observation area by measuring a change in the heterodyne interference signal when the stimulation is changed.
