Straylight and Visual Quality on Early Nuclear and Posterior Subcapsular Cataracts
(Taylor, 2016-09)
Purpose: To measure log(s) and OSI parameters, both related to forward light scattering in the eye, in subjects with different kinds of early cataracts—nuclear or posterior subcapsular—and corrected visual acuity (CVA). ...
Quantifying the effect of straylight on photopic contrast sensitivity
(Optical Society of America, 2018-07)
The visual performance of a reference group (RG) using diffuser filters was compared to a cataract-diagnosed group (CatG). Measurements of straylight (SL) parameter, photopic contrast sensitivity (CS), and visual acuity ...

Improvement of the signal-to-noise ratio in interferometry using multi-frame high-dynamic-range and normalization algorithms
(ELSEVIER SCIENCE BV, 2012-01-01)
Using both high dynamic range (HDR) and normalization methodologies, we show a method to improve the fringe pattern contrast in interferometric measurements normally used for phase recovering. In a simulated interferogram ...
Intercomparison of the LASCO-C2, SECCHI-COR1, SECCHI-COR2, and Mk4 Coronagraphs
(Springer, 2012-09)
In order to assess the reliability and consistency of white-light coronagraph measurements, we report on quantitative comparisons between polarized brightness [pB] and total brightness [B] images taken by the following ...
Calidad visual y aberraciones en visión periféricaVisual quality and aberrations in peripheral vision
(2018-03-21)
La calidad de la imagen que se genera en la retina se ve afectada principalmente por las aberraciones y la difusión intraocular mientras que la difracción solo tiene importancia para pupilas muy pequeñas. La pérdida de ...
