Optical Scanning Extrinsic Fabry-Perot Interferometer For Absolute Microdisplacement Measurement
(Optical Society of America, 1997-02-01)
We report an optical-scanning, dual-fiber, extrinsic Fabry-Perot interferometer system for absolute measurement of microdisplacement. The system involves two air-gapped Fabry-Perot cavities, formed by fiber end faces, ...
Modeling Of Fiber-Optic Sensors Based on Micromechanical Vibrations in Liquid
(Optical Society of America, 1997-08-01)
Fiber-optic chemical sensors based on optical power absorption or wavelength changes are well known. A new type of sensing element is considered. A micromechanical vibrated tiber-optic tip changes its resonance frequency ...
