Lateral chromatic aberration correction method and lens design feedback for dynamic optical tilt

Results in Optics, 2021
A method of generating lateral chromatic aberration correction factor (CACF) during lens development is presented. This CACF will be able to feedback to lens designer whether the design will work when tilt Optical Image Stabilization (OIS) compensation ...

Selecting baseline designs using a minimum aberration criterion when some two-factor interactions are important

Statistical Theory and Related Fields, 2021
This article considers the problem of selecting two-level designs under the baseline parameterisation when some two-factor interactions are important.

Holographic optical scanning elements with minimum aberrations [PDF]

Applied Optics, 1988
An analytical method to design holographic optical elements for focusing laser scanners, especially disk scanners, with minimum aberrations and optimum scan line definition is reported. The results reveal that the focused spot constraint to a straight line is always astigmatic.

Optical modelling of a supplementary tunable air-spaced goggle lens for rodent eye imaging. [PDF]

PLoS ONE, 2017
Aberration variations severely degrade retinal imaging in small animal eyes. Previously, the approach of a goggle lens with a matching corneal index was proposed to overcome the on-axis resolution limit of static imaging systems, which allows the use of ...

Vector functions for direct analysis of annular wavefront slope data

Results in Optics, 2022
In the aberration analysis of a wavefront over a certain domain, the polynomials that are orthogonal over and represent balanced aberrations for this domain are used.

Projection Uniformity of Asymmetric Fractional Factorials

Axioms, 2022
The objective of this paper is to study the issue of the projection uniformity of asymmetric fractional factorials. On the basis of level permutation and mixture discrepancy, the average projection mixture discrepancy to measure the uniformity for low ...

Enhancing gradient force over scattering force for nano-trapping through compensating for aberration

New Journal of Physics, 2023
One challenge of optical trapping of nanoparticles is the weak trapping force compared to the destabilizing pushing force. Here we enhance the optical gradient force (GF), which is responsible for trapping, to achieve stable nanoparticle trapping through

Minimum change in spherical aberration that can be perceived

Biomedical Optics Express, 2016
It is important to know the visual sensitivity to optical blur from both a basic science perspective and a practical point of view. Of particular interest is the sensitivity to blur induced by spherical aberration because it is being used to increase depth of focus as a component of a presbyopic solution.

Investigation of the Optical Properties of the Achromatic Quadrupole Lens by Using the Rectangular Potential Distribution Model

مجلة بغداد للعلوم, 2009
An optimization calculation is made to find the optimum properties of combined quadrupole lens which consists of electrostatic and magnetic lens. Both chromatic and spherical aberration coefficients are reduced to minimum values and the achromatic ...
