Minimum Aberration Split-Plot Designs Focusing on the Whole Plot Factors

open access: yesMathematics, 2022
In some experiments, the levels of some factors are difficult to change; then fractional factorial split-plot (FFSP) designs are suitable for selection.

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 ...

Holographic optical scanning elements with minimum aberrations [PDF]

open access: yesApplied 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]

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 ...

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

open access: yesNew 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
