We report on interferometric measurements of the thermo-optical aberrations of the laser medium of an Yb:YAG thin-disk laser in pumped and cw lasing conditions at several pump-power levels with a mean repeatability of 5 nm. These measurements build the basis for future intracavity compensation of the aberrations with our deformable mirror in order to improve the fundamental-mode efficiency.

INTRODUCTION Aging has various effects on visual system. Vision deteriorate, contrast sensitivity decreases and ocular aberrations apparently make the optical quality worse across the years. PURPOSE To prospective evaluate ocular aberrations along the ages. METHODS Three hundred and fifteen patients were examined, 155 were male (39.36%) and 160 were female (60.63%). Ages ranged from 5 to 64...

High-order monochromatic aberrations could potentially influence vision-dependent refractive development in a variety of ways. As a first step in understanding the effects of wave aberration on refractive development, we characterized the maturational changes that take place in the high-order aberrations of infant rhesus monkey eyes. Specifically, we compared the monochromatic wave aberrations ...

We performed measurements of refraction (with retinoscopy), axial length (with ultrasound biometry) and ocular aberrations (with a custom-built Hartmann-Shack aberrometer) on seven awake White-Leghorn chicks occluded monolaterally with diffusers for two weeks. Treatment started on the first day after hatching (day 0) and measurements were conducted on several days between day 0 and 13. Non-occl...

PURPOSE To compare the astigmatism, high order aberrations, and optical quality of the cornea after microincision (approximately 1.7 mm) versus small incision approximately 3.2 mm) cataract surgery at Eye Center, Zhejiang University, Hangzhou, China. METHODS This prospective, randomized clinical study included microincision cataract surgery and small incision cataract surgery performed on 60 ...

Zernike circle polynomials, their numbering scheme, and relationship to balanced optical aberrations of systems with circular pupils are discussed.

Aberrations limit scanning fluorescence microscopy when imaging in scattering materials such as biological tissue. Model-based approaches for adaptive optics take advantage of a computational model the optical setup. Such models can be combined with optimization techniques machine learning frameworks to find aberration corrections, was demonstrated focusing laser beam through aberrations onto c...

When using a laser guide star (LGS) adaptive optics system, quasi-static aberrations are observed between the measured wavefronts from the LGS wavefront sensor (WFS) and the natural guide star WFS. We model these LGS aberrations. c © 2007 Optical Society of America OCIS codes: (010.1080) Adaptive optics;(010.7350) Wave-front sensing.
