Sentence examples for transverse coherence from inspiring English sources

For a source of height w, with a distance R between the source and the observer, the beam is coherent over, which is defined as the transverse coherence length.

In the transverse directions, to achieve a full coherent diffraction the sample size should be smaller than the transverse coherence length, or a pinhole of size smaller than the transverse coherence length can be placed just in front of the sample.

The advent of the X-ray free electron laser (X-ray FEL) provides the additional features of ultra-short pulses and high transverse coherence, which greatly expand possibilities to study dynamic processes and to image non-crystalline materials.

In soft and hard X-rays, high longitudinal coherence, in addition to full transverse coherence, will be the key performance upgrade; ideas using laser-based or self-seeding or oscillators can be expected to be qualitatively superior to today's SASE sources.

Such an X-ray laser would allow for high-field science applications: one could make use of not only the high energy and transverse coherence of the X-ray beam, but also of the possibility of focusing it to a spot with a small radius, hopefully in the range of the laser wavelength.

The transverse coherence length L T is determined as L T == λR/2D [21].

In this study we use our previously introduced scanning laser ophthalmoscope (SLO) / transverse scanning optical coherence tomography (TS-OCT) instrument to investigate long term changes in cone photoreceptors.

We use our previously introduced transverse scanning optical coherence tomography (TS-OCT) / scanning laser ophthalmoscope (SLO) instrument that is capable to provide this 3D information with negligible eye motion artifacts due to an implemented 3D motion correction on a cellular level [ 16].

In the HNCA experiment, including the TROSY variation, the 13Cα coherence is transverse only during the chemical shift-encoding period, thus minimizing relaxation losses.

Image quality is usually assessed by standard OCT system metrics, such as axial and transverse resolution, sensitivity and coherence decay, the latter of which is also known as sensitivity roll-off [ 7, 8].

This observation is only possible because the registration between the recorded 3D data sets is better than the extension of a cone (transverse) and better than the coherence length of the light source (in depth).
