Abstract
(EN)
A first holding member (111) and a second holding member (112) are disposed as a pair so as to sandwich a measurement site (151) of a subject to be measured, and be able to hold the measurement site (151). The beam light emitted from the light emission unit (101) is introduced into the first holding member (111) by means of an optical fiber (114), passes through an optical system (115), is reflected on a reflecting portion (116), and is incident on the measurement site (151). A detection unit (102) housed in the second holding member (112) detects a photoacoustic signal generated from the measurement site (151) irradiated with the beam light emitted from the light emission unit (101). A matching member (103) is disposed in contact with the measurement site (151) between the second holding member (112) and the measurement site (151). The matching member (103) is made of a material having a prescribed acoustic impedance, which elastically deforms in a state where the elastic modulus is constant and achieves acoustic matching with the measurement site (151).

La présente invention concerne un premier élément de maintien (111) et un second élément de maintien (112) qui sont disposés en paire de manière à prendre en sandwich un site de mesure (151) d'un sujet à mesurer, et à pouvoir maintenir le site de mesure (151). La lumière de faisceau émise par l'unité d'émission de lumière (101) est introduite dans le premier élément de maintien (111) au moyen d'une fibre optique (114), traverse un système optique (115), est réfléchie sur une partie réfléchissante (116), et est incidente sur le site de mesure (151). Une unité de détection (102) logée dans le second élément de maintien (112) détecte un signal photoacoustique généré à partir du site de mesure (151) exposé à la lumière de faisceau émise par l'unité d'émission de lumière (101). Un élément d'adaptation (103) est disposé en contact avec le site de mesure (151) entre le second élément de maintien (112) et le site de mesure (151). L'élément d'adaptation (103) est constitué d'un matériau ayant une impédance acoustique prescrite, qui se déforme élastiquement dans un état dans lequel le module élastique est constant et réalise une adaptation acoustique avec le site de mesure (151).

第1保持部材(111)と第2保持部材(112)とは、対となって被測定者の測定部(151)を挾むように配置され、測定部位(151)を挟持可能とされている。第1保持部材(111)には、光出射部(101)から出射されるビーム光が光ファイバ(114)により導入され、光学系(115)を通り、反射部(116)で反射され、測定部位(151)に入射する。第2保持部材(112)に収容されている検出部(102)が、光出射部(101)から出射されたビーム光が照射された測定部位(151)から発生する光音響信号を検出する。整合部材(103)は、第2保持部材(112)と測定部位(151)との間で測定部位(151)に接して配置される。整合部材(103)は、弾性率が一定の状態で弾性変形し、測定部位(151)との間の音響整合がとれる所定の音響インピーダンスを有する材料から構成されている。
