showing spatial coherence. In both cases, the fringe amplitude slowly disappears, as the path difference increases past the coherence length. Coherence was...

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

In optics, the Arago spot, Poisson spot, or Fresnel spot is a bright point that appears at the center of a circular object's shadow due to Fresnel diffraction...

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

slit experiment is concerned with spatial coherence, while the Mach–Zehnder interferometer relies on temporal coherence. The intensity measured at the position...

arms differ less than half the coherence length of the light source. Each pixel of the CCD samples a different spatial position within the image of the...

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

from other sources of light in that it emits light that is coherent. Spatial coherence allows a laser to be focused to a tight spot, enabling applications...

are also often used directly without additional collimation. The spatial coherence guarantees a uniform wavefront prior to beam splitting. Second, it...

advantage of the low temporal coherence of SLEDs sources to achieve high spatial resolution in imaging techniques. The coherence length, Lc, is a quantity...

physicists Pieter Hendrik van Cittert and Frits Zernike, is a formula in coherence theory that states that under certain conditions the Fourier transform...

radiation, based on amplified spontaneous emission, has relatively low spatial coherence. The line is mostly Doppler broadened, which depends on the ions'...

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

This results in low temporal coherence, offering reduced speckle noise when compared with a laser. Spatial coherence can be high, however, allowing...
