Abstract

Fiber optic techniques have extended the range of engineering applications of interferometry. Example applications of intrinsic, extrinsic and full-field systems and applications are described. Intrinsic interferometric sensors are those in which the optical signal is guided in the measurement volume, and the measurand modulates the properties of the waveguide. An example is described in which optical fiber interferometers are used for measurements of heat flux and unsteady temperature in turbomachinery test rigs. Examples of extrinsic systems are those in which the displacement of a remote target surface is detected interferometrically via an air-path. Two specific cases are discussed: the detection of acoustic emission in metal-cutting processes for tool wear monitoring, and surface-profiling. Electronic speckle pattern interferometry is an example of a full-field measurement technique, and fiber optic systems for deformation, shape and vibration measurement are described.
