<p>PROBLEM TO BE SOLVED: To separate processing of contact determination and processing for image generation in a photoacoustic measuring device.SOLUTION: Acoustic wave detection means 16 includes a first detector element 161 and a second detector element 162. A photoacoustic signal detected by the first detector element 161 after light from a light source is emitted to an analyte is received by a signal processing unit, and signal processing such as image generation is performed in the signal processing unit. A reflected acoustic wave signal detected by the second detector element 162 after transmission of the acoustic wave is received by contact determination means 31. The contact determination means 31 determines whether or not a probe is brought into contact with the analyte on the basis of the received reflected acoustic wave signal.</p> |
