Improving the Generic Camera Calibration technique by an extended model of calibration display [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2014
Generic camera calibration is a method to characterize vision sensors by describing a line of sight for every single pixel. This procedure frees the calibration process from the restriction to pinhole-like optics that arises in the common photogrammetric

Multicolor Holographic Display of 3D Scenes Using Referenceless Phase Holography (RELPH)

open access: yesPhotonics, 2021
In this paper, we present a multicolor display via referenceless phase holography (RELPH). RELPH permits the display of full optical wave fields (amplitude and phase) using two liquid crystal phase-only spatial light modulators in a Michelson ...

Ist Krieg reine Männersache? (Interview mit Leandra Bias) [PDF]

open access: yes, 2022
Serie Friedensförderung, Folge 4: 27 bewaffnete Konflikte gibt es zurzeit auf der Welt, und wie immer in der Menschheitsgeschichte sind die Schlüsselakteure Männer. Ist Krieg ein Kind der Männer und können Frauen die Sicherheitspolitik verändern?

Optical In-Process Measurement: Concepts for Precise, Fast and Robust Optical Metrology for Complex Measurement Situations

open access: yesApplied Sciences, 2021
Optical metrology is a key element for many areas of modern production. Preferably, measurements should take place within the production line (in-process) and keep pace with production speed, even if the parts have a complex geometry or are difficult to ...

Qualifying parabolic mirrors with deflectometry [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2013
Phase-measuring deflectometry is a full-field gradient technique that lends itself very well to testing reflective optical surfaces. In the past, the industry’s interest has been focussed mainly on the detection of defects and ripples, since it is easy ...

The bias bias

open access: yesJournal of Business Research, 2015
AbstractIn marketing and finance, surprisingly simple models sometimes predict more accurately than more complex, sophisticated models. Here, we address the question of when and why simple models succeed — or fail — by framing the forecasting problem in terms of the bias–variance dilemma.

Catalogue of bias: publication bias [PDF]

open access: yesBMJ Evidence-Based Medicine, 2018
Dickersin and Min define publication bias as the failure to publish the results of a study ‘on the basis of the direction or strength of the study findings’.1 This non-publication introduces a bias which impacts the ability to accurately synthesise and describe the evidence in a given area.2 Publication bias is a type of reporting bias and closely ...

Improving the calibration of phase measuring deflectometry by a polynomial representation of the display shape

open access: yesJournal of the European Optical Society-Rapid Publications, 2019
Background Phase measuring deflectometry is a highly precise and full field metrology technique for specular surfaces based on the distortion of known reference patterns observed as a reflection at the surface under test.
