Motion processing deficits in migraine are related to contrast sensitivity [PDF]
, 2012 Background: There are conflicting reports concerning the ability of people with migraine to detect and discriminate visual motion. Previous studies used different displays and none adequately assessed other parameters that could affect performance, such ...

Contrast sensitivity abnormalities in deaf individuals
Journal of Ophthalmic & Vision Research, 2018 Purpose: Hearing impaired children are heavily dependent on their sense of vision to develop efficient communication skills; any contrast sensitivity defect can negatively impact their lives because they are not able to use auditory stimuli to recognize ...

Multiple-crystal X-ray topographic characterization of periodically domain-inverted KTiOPO4 crystal [PDF]
, 1995 A periodically domain-inverted KTiOPO4 crystal has been characterized for the first time by multiple-crystal multiple-reflection x-ray topography. The striation contrast within the domain- inverted regions has been revealed in high strain-sensitivity ...

Evaluating the Use of Contrast Sensitivity Tests By Orthoptists in the UK
British and Irish Orthoptic JournalIntroduction: The importance of the use of contrast sensitivity (CS) tests in orthoptic practice is well established. However, despite the clinical relevance the implementation within clinical care is known to be variable. There are no known studies that

Quantum limit of optical magnetometry in the presence of ac-Stark shifts [PDF]
, 2000 We analyze systematic (classical) and fundamental (quantum) limitations of the sensitivity of optical magnetometers resulting from ac-Stark shifts. We show that in contrast to absorption-based techniques, the signal reduction associated with classical ...

Contrast sensitivities in the Gaia Data Release 2
, 2018 The source detection sensitivity of Gaia is reduced near sources. To characterise this contrast sensitivity is important for understanding the completeness of the Gaia data products, in particular when evaluating source confusion in less well resolved ...

Visual contrast sensitivity in tonic-clonic epileptic patients [PDF]
, 2011 We measured the effects of epilepsy on visual contrast sensitivity to linear and vertical sine-wave gratings. Sixteen female adults, aged 21 to 50 years, comprised the sample in this study, including eight adults with generalized tonic-clonic seizure ...
