(Tekstil) dispersion
A process of dispersing
The degree of scatter of data
Normally refers to chromatic Disperson Chromatic Dispersion is the variation of propagation velocity - speed of travel of the light - in an optical fibre with frequency - and with wavelength - causing the pulses of light to be degraded and merge into each other as the light travels down the fibre See also PMD Different types of fibre have different Dispersion characteristics Management of Dispersion is key to network design at the fibre level
The data values in a sample are not all the same: this variation between values is called dispersion When the dispersion is large, the values are widely scattered; when it is small they are tightly clustered There are several measures of dispersion eg the standard deviation
The separation of visible light by refraction or diffraction
The dispersion of white light passing through a prism causes the well-known spectral or rainbow effect The difference in refractive index of the glass prism for red and blue light gives the mean or average dispersion figure
The cause of bandwidth limitations in an optical fiber Dispersion causes a broadening of input pulses along the length of the fiber Two major types are (a) mode dispersion caused by differential optical path lengths in a multimode fiber, and (b) material dispersion caused by a differential delay of various wavelengths of light in a wave guide material
The separation of light into its different colored rays, arising from their different refrangibilities
A measure of the `power' of a spectrograph A dimensionless number, typically given in Å mm This number arises by dividing the true length of a section of an order in the output image (in the dispersion direction) by the wavelength range covered Also the act of splitting light into its components by wavelength
The state of being dispersed; dispersedness
Hydrodynamic dispersion; the process whereby a contaminant dissolved in groundwater spreads out in the direction coincident to and perpendicular to groundwater flow, causing the contaminant to become diluted; the sum of the effects of mechanical mixing and molecular diffusion on a dissolved contaminant that results in dilution of the contaminant The mixing results from differences in flow path length and velocity for different molecules
the spatial property of being scattered about over an area or volume
The separation of a beam of light into the individual wavelengths of which it is composed by means of refraction or diffraction
The phenomenon in an optical fiber whereby light photons arrive at a distant point in different phase than they entered the fiber Dispersion causes receive signal distortion that ultimately limits the bandwidth and usable length of the fiber cable The two major types of dispersion are 1) mode (or modal) dispersion caused by differential optical path lengths in a multimode fiber, and 2) material dispersion caused by differing transmission times of different wavelengths of light in the fiber optic material
The dependence of the velocity of a wave on the frequency of the wave is known as dispersion A media in which waves of different frequencies propagate at different speeds is said to be dispersive
The tendency of light to scatter spatially when refracted through a dielectric medium whose index of refraction varies with wavelength (See also Hartmann constant )
the spreading of white light into the full spectrum
The process of separating polychromatic light into its component wavelengths
Dispersion is the spreading of people or things over a wide area. The threat will force greater dispersion of their forces. dispersal. Any phenomenon associated with the propagation of individual waves at speeds that depend on their wavelengths. Wavelength determines the speeds at which waves travel through media. This variation in speed causes radiation to separate into components that have different frequencies and wavelengths. For example, when a beam of white light is sent through a glass prism, refraction causes the beam to disperse into an array of its component colours of light, producing a rainbowlike effect
