Dispersion measuring techniques
نویسنده
چکیده
A study of chromatic dispersion (CD) in optical fibers, its effects on signal propagation, the devices to compensate it and the methods for its characterization. We have presented the experimental setups for the most popular frequency domain methods for CD measurement, Peucheret and Modulation Phase Shift Method (MPSM), as well as for an advanced method with improved performance, the Asymmetric Mode and Bias Control method (AMBC), whose theoretical basis have also been described. Experimental measures of the D parameter of CD for both 75km of standard single-mode fiber and a Dispersion Compensating Fiber Bragg Grating (DC-FBG) with all 3 methods have shown good agreement.

متن کاملMoving dispersion method for statistical anomaly detection in intrusion detection systems
A unified method for statistical anomaly detection in intrusion detection systems is theoretically introduced. It is based on estimating a dispersion measure of numerical or symbolic data on successive moving windows in time and finding the times when a relative change of the dispersion measure is significant. Appropriate dispersion measures, relative differences, moving windows, as well as tec...

متن کاملMeasurement of radial velocities and velocity dispersion of stars in circumnuclear regions of galaxies using the 2D spectrosopy technique
A procedure is described of construction of velocity fields and velocity dispersion of the stellar component in the central regions of galaxies on the basis of data obtained with the integral field spectrograph MPFS. Cross-correlation and Fourier quotients techniques adapted for 2D spectra reduction are used. A detailed discussion is given of the problems of providing for the instrumental profi...
متن کاملQuantifying Gas Phase Dispersion in Soil Media
Hydrocarbon contamination of unsaturated soils has been a serious environmental problem for decades. Two of the most common methods of remediating these sites are soil vapour extraction (SVE) and bioventing. Predictive models have been developed for the SVE and bioventing processes in order to estimate mass transfer coefficients for experimental systems and clean up times for field sites. These...
