All-fiber-optic remote sensing of temperature employing interferometric techniques.
An all-fiber interferometric temperature sensor capable of remote operation is described in which the fiber's sensing element is configured as a Fabry-Perot cavity of typically less than 5 mm situated at the end of a lead fiber of arbitrary length (typically 2 m). The sensing element is addressed through a fiber coupler, permitting both remote detection and multiplexing of a number of sensing elements for multiple-point measurements.
