This optical biometric device (1) is equipped with: a plurality of light-transmitting probes (12) and light-receiving probes (13) to be arranged on the surface of the scalp of a subject to be tested; a transmitting/receiving-light control unit (21) for obtaining a plurality of units of received-light-amount information pertaining to a plurality of measurement sites, by controlling in a manner such that the light-transmitting probes (12) emit light onto the scalp surface, and the light-receiving probes (13) detect light emitted from the scalp surface; a calculation unit (22) for obtaining a plurality of measurement data on the basis of the plurality of units of received-light-amount information; and a correlation-coefficient calculation unit (23) for calculating a correlation coefficient expressing the strength of the correlation between each measurement datum. This optical biometric device (1) is further equipped with: a 3D-image-display control unit (32) for obtaining and displaying a 3D-scalp-surface image (41) and/or a 3D-brain-surface image (42); and a correlation-coefficient-display control unit (24) for displaying the measurement points from which measurement data is obtained, on the 3D-scalp-surface image (41) and/or 3D-brain-surface image (42), and also displaying in a manner such that a line segment expressing the size of the correlation coefficient connects the measurement points. |
