摘要 |
An optical fiber temperature sensor including an optical fiber (1) which has a mirror (3) at its end, and which is associated with temperature-sensitive means, means for launching a signal into said fiber and means for receiving the signal reflected by said mirror back along the fiber, said temperature-sensitive means being a section of amplifying optical fiber (10) bonded to said optical fiber (1), cooperating with a light pump source, and doped with a chosen rare-earth element.
