Fiber coupler displacement transducer |
摘要 |
A transducer for the measurement of minute displacements incorporates a fiber optic coupler having a coupling efficiency which varies in relation to the relative position of coupler elements. The transducer may also be used indirectly as an accurate sensor of physical parameters, such as temperature and pressure, through the use of a secondary transducer which provides a displacement proportional to such physical parameter. The outputs from the fiber optic coupler may be compared to provide a measure of the coupling efficiency, and may be monitored by a display which provides a direct measurement of displacement or a secondary physical parameter.
