Dispersion, английский
- Увеличение ширины импульса сигнала при его распространении по оптоволокну. основной фактор, ограничивающий полосу пропускания многомодового оптоволокна.
- Дисперсия.
- Эффект расширения световых импульсов во время их передачи по оптическому волокну. дисперсия пропорциональна длине кабеля (см. также хроматическая дисперсия).
- Refers to the spread of values observed for a variable. the standard deviation is a measure of dispersion, in contrast to the mean which is a measure of central tendency or location.
- The cause of bandwidth limitations in fiber. in multimode systems, modal dispersion is caused by differential optical path lengths known as differential path delay. for singlemode systems, chromatic dispersion is a combination of material dispersion (caused by the line width of the laser source) and waveguide dispersion (caused by the difference in the speed of light in the core and the cladding of the fiber). another type of dispersion is polarization mode dispersion (pmd), which is caused by random vibration, temperature variations, and bending of the fibers known as birefringence
- (1) the variation in the refractive index of a medium as a function of wavelength. (2) the property of an optical system which causes the separation of the monochromatic components of radiation.
- The dependence of the phase velocity in a medium on the optical frequency or the propagation mode
- The stretching of light pulses as they travel in an optical fiber, which increases their duration. the temporal spreading of a light signal in an optical waveguide caused by light signals traveling at different speeds through a fiber either due to modal or chromatic effects.
- This occurs when white light is split into separate wave lengths and component colors.
- Модовая дисперсия dispersion-compensating fiber волокно с компенсацией дисперсии
- Also known as "fire," dispersion refers to the separation of white light into different colors.
- Separation of white light into spectral colours, each of which vibrates at a different frequency. also called fire.
- Sometimes referred to as fire, dispersion is the break-up of white light into a spectrum of colors.
- 1. a system consisting of finely divided particles and the medium in which they are distributed. 2. separation of light into colors by diffraction or refraction. 3. a qualitative estimation of the separation and uniform distribution of fibers in the liquid during the production of a wet-formed nonwoven fabric.
- Losses`, pi потери воды при капельном орошении за счет фильтрации за пределы очага увлажнения
- The separation of light of different frequencies due to different degrees of refraction
- In acoustics, variation of wave phase with frequency.
- In acoustics, variation of wave phase with frequency.7
Spectroscopy, английский
- Methods where the interaction of light with matter is utilized
- Спектроскопия ко к данному компоненту пробы, а не к каким-либо другим присутствующим ингредиентам.
- Спектроскопия. раздел физики, посвященный изучению спектров. менее распространенный термин спектрометрия может относиться к методам их количественного измерения, а термин спектрография относится к методам, в которых используется фоторегистрация и другие виды записи. применение спектроскопических методов в области аналитической химии получило название спектрального химического анализа. все эти методы основаны на взаимодействии электромагнитного излучения с веществом и обнаружении квантов энергии, испускаемых или поглощаемых при переходе вещества из одного энергетического состояния в другое. эмиссионная спектроскопия изучает спектры, образующиеся при дисперсии излучения, испускаемого возбуждаемым источником, абсорбционная спектроскопия — спектры, образующиеся , при поглощении (при определенных длинах волн) энергии излучения, испускаемого непрерывно действующим источником. для изучения спектральных линий атомов при- 9* 131
- The identification of materials by the analysis of their spectra.
- Spectrophotometry or spectroradiometry in which the spectrum, rather than being analyzed only by a processing unit, is presented as a digital signal for computer analysis or in a visible form to the operator for organoleptic examination.
- Spectrophotometry or spectroradiometry in which the spectrum, rather than being analyzed only by a processing unit, is presented in a visible form to the operator for organoleptic examination.
- The study of how radiant energy and a medium interact with respect to wavelength or frequency. see also polychromator spectrometer; spectrofluorometer; spectrophotometer; spectroradiometer.
