Abstract: Contrast transfer function (CTF) is a vital in transmission electron microscopy (TEM). It expresses to what extent amplitudes converted from the phase changes of diffracted waves contribute TEM image, including effects lens aberrations. Simulation very helpful understand application thoroughly. In this work, we develop CTFscope as component Landyne software suite, calculate CTF with t...

For five consecutive eyes from five patients with liquefied aftercataract, Nd:YAG laser treatment significantly reduced high-order aberrations. Two eyes showing a reduction in positive spherical-like aberrations after treatment showed a postoperative myopic shift, while three eyes showing no change in spherical-like aberrations demonstrated hyperopic or only a slight myopic shift.

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...

The use of a multichannel wavefront sensor matched with phase Zernike functions to determine the type and magnitude aberration in analyzed is investigated. approach based on stepwise compensation aberrations dynamically tunable spatial light modulator. As criteria for successful detection, not only correlation peak, but also maximum intensity, compactness, orientation distribution each diffract...
