Universal algorithm for water depth refraction correction in through-water stereo remote sensing
International Journal of Applied Earth Observations and Geoinformation, 2020 In through-water stereo remote sensing, the correction of the effect of light refraction on water depth determination is an unsolved problem. The challenge is that no solution exists for apparent positions when the conjugate image rays are non ...

Corneal Crosslinking in Refractive Corrections
Translational Vision Science & Technology, 2021 The clinical application of corneal crosslinking relies on a good understanding of the biomechanical effect of various treatment parameters on corneal tissue. We discuss the results of the clinical and laboratory studies evaluating corneal crosslinking as a primary refractive treatment.

Modeling refractive correction strategies in keratoconus
Journal of Vision, 2021 This work intends to determine the optimal refractive spectacle and scleral lens corrections for keratoconus patients using the visual Strehl (VSX) visual image quality metric and the SyntEyes models with the synthetic biometry of 20 normal eyes and 20 keratoconic eyes. These included the corneal tomography and intraocular biometry. A series of virtual

Glare and halo with refractive correction [PDF]
Clinical and Experimental Optometry, 2008 The aim of this investigation was to compare glare and halo with various methods of refractive correction.Ninety-eight eyes of healthy pre-presbyopes were analysed for the presence of glare and halo using computer-generated stimuli. Subjects were divided into three groups: emmetropes without correction, single vision plastic lens spectacle wearers ...

Can the red-green duochrome test be used prior to correcting the refractive cylinder component? [PDF]
PLoS ONE, 2015 A primary task of the eye care professional is determining the refraction, or optical correction, of a patient. The duochrome red-green test is a standard tool for verification of the final refraction.

Compensation for phase distortions in nonlinear media by phase conjugation [PDF]
, 1980 We demonstrate theoretically that the distortion-correction property of phase-conjugate beams propagating in reverse through aberrating media is also operative when the indices of refraction of the media depend on the intensity.

The Refraction Correction of Elevation Angle for the Mean Annual Global Reference Atmosphere
International Journal of Antennas and Propagation, 2020 In some frequency-sharing studies between fixed service and space radiocommunication services, including fixed-satellite, broadcasting-satellite, and space science services, it is necessary to estimate the apparent elevation angle of a space station ...
