Sentence examples for source grating from inspiring English sources

Except for the additional OCT-specific components (OCT light source, grating), none of the optics of the confocal microendoscope were replaced.

A source grating (G0) renders the method accessible with a clinical x-ray source by providing the beam coherence necessary for the method.

For quasi-monochromatic sources, we derive an analytical formula and demonstrate that the visibility can reach 100% if the duty cycle of the source grating is less than an explicitly given bound.

The source grating G0 provides the necessary beam coherence for interference effects to occur with a clinical x-ray source, the phase grating G1 causes a periodic modulation of the interference pattern, and the analyser grating G2 enables the resolution of the pattern with a conventional detector.

A three-grating Talbot-Lau interferometer consisting of a conventional X-ray tube, a source grating G0, a phase grating G1 and an analyser grating G2 (Microworks GmbH, Germany) was used for the experimental measurements.

The three gratings as displayed in the sketch in Fig. 1 a comprise the so-called Talbot Lau interferometer: The source grating G0 counteracts the incoherence of the extended and polychromatic conventional x-ray source by creating an array of smaller line sources that exhibit sufficient coherence.

The photocurrent (PC) spectra were investigated under monochromatic light dispersed from a glowbar source by grating spectrometer and chopped at a frequency of 233 Hz.

According to the phase stepping method (Weitkamp et al., 2005), for each angular gantry position a set of five images with varying source-grating position was recorded applying an exposure of 5 s.

From measurements of a single crystal silicon sample using the same instrument configuration (slit width, grating and excitation source), we estimate a spectral resolution from the bandwidth of the main Si scattering peak of 4.6 cm−1 or better.

The contact grating technology based on ZnTe or other semiconductors can be an efficient source of intense THz pulses with mJ-level energy.

The XANES measurements were conducted on the high resolution spherical grating monochromator (SGM) [21] and variable line spacing plane grating monochromator (VLS PGM) [22] beamlines at the Canadian Light Source synchrotron facility.
