Constrained realizations of Gaussian fields : a simple algorithm
Yehuda Hoffman,Erez N. Ribak +1 more
TL;DR: A straightforward method for the construction of constrained realizations of Gaussian fields is presented, based on a simple construction of this residual field, which is then added to the analytically calculated mean field.
Journal ArticleDOI
Simulated annealing in ocular adaptive optics.
TL;DR: This work presents what is to their knowledge a first hardware realization of a simulated annealing algorithm in an adaptive optics system designed to image the retina of the human eye and finds that this optimization algorithm can be an alternative to the traditional Hartmann-Shack sensing.
Journal ArticleDOI
Müller cells separate between wavelengths to improve day vision with minimal effect upon night vision
TL;DR: It is shown that Müller cells are wavelength-dependent wave-guides, concentrating the green-red part of the visible spectrum onto cones and allowing the blue-purple part to leak onto nearby rods.
Journal ArticleDOI
Turbulence-degraded wave fronts as fractal surfaces
TL;DR: In this article, the authors identify wave fronts that have passed through atmospheric turbulence as fractal surfaces from the Fractional Brownian motion family, which can be attributed to both the spatial and the temporal behavior.
Journal ArticleDOI
Phase retrieval by demodulation of a Hartmann–Shack sensor
Yuval Carmon,Erez N. Ribak +1 more
TL;DR: A method for retrieving the wavefront from a Hartmann–Shack sensor using a two-dimensional Fourier demodulation technique that provides both phase gradient components in real space and the robustness of the technique to Poisson and white noise is discussed.
