Fiber optic measurement systems are on the cutting edge of instrumentation for many industries from military and government applications to commercial needs such as the automotive, aerospace, and power turbine industries. Measurement parameters including temperature, pressure, and strain can provide valuable information. Sensor mapping allows for larger scale monitoring capabilities and provide flexibility in sensing applications. A sensor and readout system is being developed to expand the capabilities of fiber optic sensing. Several iterations of multiplexed sensors have been tested using a high-resolution fiber optic coupled dual Michelson interferometer based-instrument that has the capability of reading gaps of 25μm to 6.5mm. This measurement range opened the opportunity to read several different sensors on the same fiber, i.e. the same channel. Sensor strings combining temperature and strain extrinsic Fabry-Perot interferometric sensors were tested. These sensor strings produced were either serial multiplexed, parallel multiplexed, or a combination. This paper will discuss the capabilities of the sensors and instrumentation systems developed.
