Photoacoustic measuring apparatus

Abstract

Provided is a photoacoustic measuring apparatus. The apparatus comprises a light source configured to emit laser of a predetermined wavelength to a measurement target, a photoacoustic detector configured to detect a photoacoustic signal generated from the measurement target receiving the laser light emitted from the light source, a contact sensor including a first bioimpedance electrode, a second bioimpedance electrode, and a third bioimpedance electrode and configured to obtain a bioimpedance value when the electrodes come into contact with the measurement target and an operator during use of the photoacoustic measuring apparatus, and a controller configured to decide whether the apparatus is in proper contact with the measurement target and whether the operator and the measurement target are the same individual based on a bioimpedance value measured using the contact sensor.

Dependencies are inferred from the claim text.
