Blocked regular fractional factorial designs with minimum aberration [PDF]

open access: yesThe Annals of Statistics, 2005
This paper considers the construction of minimum aberration (MA) blocked factorial designs. Based on coding theory, the concept of minimum moment aberration due to Xu [Statist.

Minimum aberration designs for discrete choice experiments [PDF]

open access: yesJournal of Statistical Theory and Practice, 2017
A discrete choice experiment (DCE) is a survey method that givesinsight into individual preferences for particular attributes.Traditionally, methods for constructing DCEs focus on identifyingthe individual effect of each attribute (a main effect ...

Patterning Fidelity Enhancement and Aberration Mitigation in EUV Lithography Through Source–Mask Optimization [PDF]

open access: yesMicromachines
Extreme ultraviolet (EUV) lithography faces critical challenges in aberration control and patterning fidelity as technology nodes shrink below 3 nm. This work demonstrates how Source–Mask Optimization (SMO) simultaneously addresses both illumination and ...

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.

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

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

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 ...

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

open access: yesStatistical 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]

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 ...
