Accuracy and reproducibility of biometry using partial coherence
The partial coherence
of the light over the sample is determined by the Van Cittert-Zernike theorem (Born & Wolf, 2005) what stablish that the diameter of the area almost coherently illuminated is given by [D.
Technically, OCT is a partial coherence
The author has organized the main body of his text in nine chapters devoted to random variables, random processes, first-order properties of light, the temporal and spatial coherence of optical waves, problems involving higher-order coherence, the effects of partial coherence
in imaging systems, and a variety of other related subjects.
Advanced aero-acoustic measures including partial coherence
techniques, orthogonal beam forming and deconvolution beam forming will be utilized to fully assess the noise emission of the landing gear.
Nevertheless, this kind of method is directly to use Fourier inversion algorithm for solving the approximate brightness temperature distribution, and ignores the visibility observation error caused by the antenna position errors, and partial coherence
between the radiation sources and some other factors.
s] is the source coherence parameter, which is the degree of the partial coherence
of the source laser beam at the transmitter.
If these precautions are not taken the theory of partial coherence
may have to be used for the computations.
Beam wander, the theory of partial coherence
of the source, and phase fluctuations are also covered.
Another effect of the initial Rosslyn validation was the development of a fully three-dimensional (3D) ray model that accommodates arbitrarily oriented building and terrain faces and provides results with full vector fields and, if desired, rays combined with full phase information, This model also allows the user to combine rays with no coherence, partial coherence
or full coherence.
laser interferometry vs conventional ultrasound biometry in intraocular lens power calculations.
8) compared the keratometry results obtained with Scheimpflug camera imaging (Pentacam, Oculus, Germany), corneal topography, or partial coherence
interferometer (PCI) for intraocular power calculations in cataract surgery.
