<p>PROBLEM TO BE SOLVED: To provide an optical fiber probe of a laser rheometer which enables installing of an optical fiber parallel with a surface to be measured by fixing a reflector at the tip of the optical fiber. SOLUTION: This rheometer is provided with a rheometer body, an optical fiber 2 for irradiation and an optical fiber 3 for photodetecting and a probe P on which are fixed the tip parts of the optical fiber 2 for irradiation and the optical fiber 3 for photodetecting. In this case, a reflection fixed plate 10 is provided having a fixing means 11 for fixation on a tissue of a living being and the optical fiber 2 for irradiation and the optical fiber 3 for photodetecting are fixed parallel on a reflection surface 10a of the reflection fixed plate 10 to form the probe P. A laser light outputted from the optical fiber for irradiation and scattered light within the tissue of the living being are reflected on the reflection surface of the reflection fixed plate. A reflector 13 is stuck on an elastic body 13 to form the reflection fixed plate 10.</p> |
