Interferometry has been a time-honored technique for surface topography measurement. Interferometric measurements of surface shape are relative measurement techniques in which the shape of a known Author: Dahi Ghareab Abdelsalam, Baoli Yao. When the first edition of Optical Interferometry was published, interferometry was regarded as a rather esoteric method of making measurements, largely confined to the laboratory. Today, however, 5/5(1). Advanced Search >. Home > Proceedings > Volume > Article > Proceedings > Volume > ArticleCited by: 1. In this paper, an extrinsic Fabry–Perot interferometer (EFPI) has been demonstrated for strain measurements. A monochromatic light source with a wavelength of nm is propagated into Cited by: 3.

A fiber-optic Fizeau interferometer with active path length stabilization has been developed to monitor broadband ultrasonic displacements. Absolute displacement sepsitivity of 50 pm has been obtained . Phase Detection Change in length due to mechanical or thermal strain will cause a phase change (Mach-Zehnder interferometer) Provides extremely high resolution Noise issues such as phase noise and . A novel Fiber Optic Sound Sensor (FOSS) for detecting military targets was presented. The principle of the FOSS was based on Michelson interferer technology and the transducer was made of a plate.
