PROBLEM TO BE SOLVED: To provide an optical fiber temperature distribution measuring device capable of integrating an exciter even in a comparatively small space which is approximately similar to a conventional case, and measuring an accurate temperature distribution by removing a higher mode.SOLUTION: In an optical fiber temperature distribution measuring device using an optical fiber as a sensor, and constituted so as to measure a temperature distribution along the optical fiber by utilizing Raman back-scattered light, an exciter is constituted by two-dimensionally wiring the optical fiber.SELECTED DRAWING: Figure 1 |
