A novel design for a Fabry-Perot Interferometric Sensor (FPIS) consisting of a Fabry-Perot cavity formed between two bonded surfaces is discussed. The Fabry-Perot cavity and the optical fiber to which it is coupled are used as the sensing element and interconnect, respectively. The Fabry-Perot cavity is fabricated using the Micro Electro Mechanical Systems (MEMS) technology. The introduction of a center rigid body diaphragm gives this sensor considerable advantage when compared with previous Fabry-Perot cavity based sensors.

Interferometric Sensor

A novel optical fiber sensing technique for length and temperature measurement with accuracy of sub-nanometer and 10-4° C , respectively, is proposed. The new kind of sensor is a combination of a conventional interferometric sensor and a hybrid optical bistable device. The measurement is accomplished by counting the number of electrical pulses, provided by switching on and switching off of the optical bistability periodically. An optical bistable fiber sensor with a March–Zehnder interferometer is analyzed in this paper. The main advantages of this technique lie in the adjustable high accuracy and ability to distinguish the variation direction of quantities to be measured.
