Abstract
The present disclosure is a light reflection measurement device including: a first light source for outputting first continuous light; a second light source for outputting second continuous light as local light; and a signal processing unit for performing digital signal processing on a light reception signal I(t) obtained by multiplexing reflected light that is obtained by irradiating a measurement target with one branched light of the first continuous light, reference light that is the other branched light of the first continuous light, and the local light, in which the signal processing unit calculates an autocorrelation function between the light reception signal I (t) and a light reception signal I (t+τ) obtained by shifting the light reception signal by time τ, and measures reflection on the measurement target by using a position of a peak of the autocorrelation function.
