\Delta \lambda \,} is the width of the range of wavelengths in the signal. In optical communications and optical coherence tomography (OCT), assuming...

For an electromagnetic wave, the coherence time is the time over which a propagating wave (especially a laser or maser beam) may be considered coherent...

Optical coherence tomography (OCT) is an imaging technique that uses interferometry with short-coherence-length light to obtain micrometer-level depth...

maintain coherence until diffraction. It has been shown that the coherence width of the incident beam needs to be approximately twice the lateral width of the...

its wavelength and coherence length. The coherence length determines the width of the correlogram, which relies on the spectral width of the light source...

continues to decrease without bound. Both transverse and longitudinal coherence widths (packet sizes) of such high energy electrons in the lab may be orders...

diodes with the low coherence of conventional light-emitting diodes. Its emission optical bandwidth, also described as full-width at half maximum, can...

convolution kernel used in statistics Graph bandwidth, in graph theory Coherence bandwidth, a frequency range over which a channel can be considered "flat"...

the coherence is with respect to the phase of the atom's de Broglie wave. If an electron in a two level atomic system is excited by narrow line width coherent...

correlated is called the coherence length. In order for interference to occur, the path length difference must be smaller than the coherence length. This is sometimes...

are spatial coherence and spectral coherence. While spatial coherence is related to the beam divergence of the laser, spectral coherence is evaluated...

scales as σ 2 2 / a 3 {\displaystyle \sigma _{2}^{2}/a^{3}} , so the coherence length is approximately 1/FWHM for the first peak. B.D. Cullity & S.R...

have high temporal coherence, which permits them to emit light with a very narrow frequency spectrum. Alternatively, temporal coherence can be used to produce...

partial coherence factor, or σ {\displaystyle \sigma } . It also affects the pattern quality and hence the application of OPC. The coherence distance...

progressively lower resolution representation of the previous. The height and width of each image, or level, in the mipmap is a factor of two smaller than the...

significant undercutting of the photoresist pattern. This is essential when the width of the features to be defined is similar to or less than the thickness of...

it is required that the differential pathlength is reduced below the coherence length of the light source. That can be only micrometers for white light...

technique used to measure the coherence. These DFB fibre lasers are often used in sensing applications where extreme narrow line width is required. "The World's...

beams of similar quality in terms of spatial coherence (a single-mode Gaussian beam) and long coherence length (however, since about 1990 semiconductor...

are determined by two parameters: the waist w0, which is a measure of the width of the beam at its narrowest point, and the position z relative to the waist...
