Two spatial light modulators (SLMs) are utilized for beam splitting, steering and tracking. Both linear and holographic phase screens are used in a demonstration of technology to allow real time tracking to communicate in a one-to-several type scenario. One SLM is used to apply a linear phase modulation to steer multiple beams onto a detector. The spots that are produced represent the targets a...

Zero curvature formulations, pseudo-potentials, modified versions, “Miura transformations”, and nonlocal symmetries of the Korteweg–de Vries, Camassa–Holm and Hunter–Saxton equations are investigated from an unified point of view: these three equations belong to a two–parameters family of equations “describing pseudo-spherical surfaces”, and therefore their basic integrability properties can be...

در ابتدا به طور مختصر ارتباط بین مسائل تغییراتی و معادلات دیفرانسیل را بیان می کنیم. همان طور که می دانیم هر معادله دیفرانسیل را می توان به صورت ‎egin{equation} label{yek}‎ ‎a(u)= 0‎ ‎end{equation}‎ نوشت، که در آن ‎$ a(u) $‎ یک عملگر دیفرانسیل معمولی یا جزئی خطی یا غیرخطی و ‎$ u $‎ مجهول می باشد. برای حل این معادلات و به خصوص معادلات دیفرانسیل جزیی غیرخطی راه حل مشخصی وجود ندارد.حساب تغییر...

The Cimmino algorithm is an iterative used for solving linear equations ( Ax = b ) and part of a wider family algebraic reconstruction algorithms. Despite being in computed tomography digital signal processing, we present approach using it holographic projections the Fraunhofer region. Following work carried out by our group on Kaczmarz holography, earlier equation solver, compare performance s...

We show that the continuous limit of a wide natural class of the right-invariant discrete Lagrangian systems on the Virasoro group gives the family of integrable PDE's containing Camassa-Holm, Hunter-Saxton and Korteweg-de Vries equations. This family has been recently derived by Khesin and Misio lek as Euler equations on the Virasoro algebra for H 1 α,β-metrics. Our result demonstrates a unive...

A variety of approaches to wavefront sensing and reconstruction are surveyed as they are used in adaptive optics and related applications. These include the Gerchberg-Saxton algorithm; shearing interferometry; and Shack-Hartmann, curvature, and pyramid wavefront sensing. Emphasis is placed on the relevant optics and mathematics, which are developed in some detail for Shack-Hartmann and curvatur...
