Characterization And Modeling Of Drift Noise in Fourier Transform Spectroscopy: Implications For Signal Processing And Detection Limits
(Optical Society of America, 1997-05-01)
A theoretical analysis of long-term drift noise in Fourier transform spectroscopy is presented. Theoretical predictions are confirmed by experiment. Fractional Brownian motion is employed as a stochastic process model for ...
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 ...
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, ...
Investigation And Application Of The Frustrated-Total-Internal-Reflection Phenomenon in Optical Fibers
(Optical Society of America, 1997-12-01)
A detailed investigation of the frustrated-total-internal-reflection (FTIR) phenomenon in silica-glass-based optical fibers and its application to simple intensity-modulated strain and pressure sensors is presented. Such ...
Layer-by-layer electrostatic self-assembly of nanoscale Fe3O4 particles and polyimide precursor on silicon and silica surfaces
(AIP Publishing, 1997-10-01)
Monolayer and multilayer ultrathin films comprised of nanosized iron oxide (Fe3O4) particles and polyimide molecules have been fabricated on single crystal silicon and quartz substrates by a novel layer-by-layer electrostatic ...
