Minimum aberration blocked designs with multiple block variables [PDF]

open access: bronzeMetrika, 2020
Blocked fractional factorial designs are used to treat inhomogeneity of the experimental units. Mostly (and for simplicity) blocked designs with a single block variable can be found in the literature. In practice, however, inhomogeneity often comes from multiple block variables.

Minimum change in spherical aberration that can be perceived

open access: goldBiomedical 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.

Bayesian-inspired minimum contamination designs under a double-pair conditional effect model

open access: yesStatistical Theory and Related Fields, 2023
In two-level fractional factorial designs, conditional main effects can provide insights by which to analyze factorial effects and facilitate the de-aliasing of fully aliased two-factor interactions. Conditional main effects are of particular interest in

Active Alignment of Large-Aperture Space Telescopes for Optimal Ellipticity Performance

open access: yesSensors, 2023
Ellipticity performance of space telescopes is important for exploration of dark matter. However, traditional on-orbit active optical alignment of space telescopes often takes “minimum wavefront error across the field of view” as the correction goal, and

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

open access: yesResults 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 ...

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

open access: yesPLoS 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

open access: yesResults 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

open access: yesAxioms, 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 ...
