Abstract: According to the present invention, a measurement device includes a light emitting part configured to emit a plurality of spectral lights each including two or more spectra distributed at mutually different frequencies by causing adjacent frequency intervals to be different from each other, a focusing part configured to focus light by causing two or more spectra to overlap in an overlapping region in each of a plurality of different focal point regions of a sample and to be shifted from each other, and a detecting part configured to acquire a signal of fluorescence beats which emits light by interference light beats in each of a plurality of overlapping regions in the sample and includes information of the sample.
