| 摘要 |
An optical fiber moisture sensor comprising a mechanical system having a stationary jaw and a moving jaw between which said fiber is mounted, the sensor also including an element made of moisture-sensitive material coupled to said moving jaw to allow it to be urged towards said stationary jaw in the presence of moisture, thereby applying compression to said optical fiber, wherein said element is made of a material that looses mechanical strength with increasing moisture and that is mounted to oppose the action of resilient means urging said moving jaw towards said stationary jaw.
