MINIATURE FIBER OPTIC TEMPERATURE SENSORS |
摘要 |
An intensity-based fiber optic temperature sensor having a fiber probe with a multimode transmit/receive fiber, a reflector spaced apart from the end of the fiber, and a housing affixed at its ends to the fiber probe and reflector, the housing having a larger or smaller thermal expansion coefficient than those of the fiber probe and reflector. Temperature changes cause a change in the gap distance between the fiber end and the reflector, changing the amount of reflected light coupled into the optical fiber. Temperature sensors can also have a fiber probe with two or more multimode receiving fibers surrounding a transmitting fiber. Other temperature sensors include a fiber probe with a multimode transmitting fiber, a reference multimode receiving fiber and a sensing multimode receiving fiber for reducing noise effects.
