| 摘要 |
The invention concerns a temperature sensor including an optical fiber source (10, 30) for supplying an optical signal, a first fiber optic transmission line (12, 32) connected to the optical source, a sensitive optical fiber portion (14, 34) connected to the fiber optic transmission line, a second fiber optic transmission line (16, 36) connected to the sensitive portion of the optical fiber, and an optical detection and processing circuit (18, 38) connected to the second fiber optic transmission line for receiving and analysing the optical signal transmitted by the optical source and passing through the optical fiber, said sensor being characterised in that said sensitive optical fiber portion is mounted on a plane support and bent over a determined length (N1) and with a determined amplitude of curvature (A1).
