PROBE FOR DETECTING SOUND SIGNAL, AND PHOTOACOUSTIC MEASURING DEVICE INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a probe to which a sound signal processing unit and a light source unit are connected without complicatedness in setting a photoacoustic measuring device.SOLUTION: A probe 11 connected to a sound signal processing unit 12 and a light source unit 13, respectively to be used for detecting a photoacoustic wave U from a subject M includes: a probe body 11a having a sound detecting part 42 for detecting a photoacoustic wave U and a light irradiation part 41 for applying light L to the subject M; a sound signal line 44 for transmitting a photoacoustic signal of the photoacoustic wave U detected by the sound detecting part 42; a light guide part 40 for guiding the light L emitted from the light source unit 13 to the light irradiation part 41; and a control signal line 62 connecting between the sound signal processing unit 12 and the light source unit 13.
