Sentence examples for effective focal spot from inspiring English sources
We demonstrate an effective focal spot size of 209 nm in lateral and 551 nm in axial direction.
Almost exclusively, X-ray sources with effective focal spot sizes of <10 μm, which are commercially available, employ electrostatic or magnetic focussing and require high beam current pulsing techniques, to prevent limitation in their imaging resolution by motion-induced blurring [206].
However, NLOM using near-IR light has a lower spatial resolution than linear optical microscopy employing visible light because the effective focal spot size depends more on the wavelength than the intensity.
We measure the effective excitation PSF by probing the focal spot at different positions.
In this study, a standard GRIN lens with pitch of 0.25 was shortened to 0.15 in order to achieve longer effective focal length, which enables a smaller spot size for the long working distance.
In the case of a 1,550 nm fractional erbium-glass laser, the total energy is sum of the fluence (pulse energy per effective focal area) multiplied by the total density (treatment spots per square centimeter) in every shot.
A large electron beam focal spot will create a penumbra effect where the X-ray spot subtends a significant angle at the subject; this blurs the resultant image.
The concentrated solar power at the focal spot of a primary parabolic mirror with 1.18 m2 effective collection area was efficiently coupled to the entrance aperture of a 2D-CPC/2V-shaped pump cavity, within which the thin laser rod was pumped.
Even so, the focal spot and coagulative necrosis can be effectively judged using US imaging.
Nonlinear effects that would normally result in focal plane shifts and focal spot distortion are mitigated when SSTF is employed.
