Long-term Visual and Refractive Outcomes of Argon Laser-treated Retinopathy of Prematurity
Journal of Ophthalmic & Vision Research, 2022 Purpose: In this case–control study, we measured visual acuity, objective refraction, ocular biometric parameters, and strabismus in premature cases classified according to the following categories: argon laser-treated retinopathy of prematurity (ROP ...

Optical coherence refraction tomography
Nature Photonics, 2019 Optical coherence tomography (OCT) is a cross-sectional, micrometre-scale imaging modality with widespread clinical application. Typical OCT systems sacrifice lateral resolution to achieve long depths of focus for bulk tissue imaging, and therefore tend ...

Numerical simulations of negative-index refraction in wedge-shaped metamaterials [PDF]
, 2005 A wedge-shaped structure made of split-ring resonators (SRR) and wires is numerically simulated to evaluate its refraction behavior. Four frequency bands, namely, the stop band, left-handed band, ultralow-index band, and positive-index band, are ...

RBF-Based Camera Model Based on a Ray Constraint to Compensate for Refraction Error
Sensors, 2023 A camera equipped with a transparent shield can be modeled using the pinhole camera model and residual error vectors defined by the difference between the estimated ray from the pinhole camera model and the actual three-dimensional (3D) point.

Liquid crystal hyperbolic metamaterial for wide-angle negative-positive refraction and reflection [PDF]
, 2014 We show that nanosphere dispersed liquid crystal (NDLC) metamaterial can be characterized in near IR spectral region as an indefinite medium whose real parts of effective ordinary and extraordinary permittivities are opposite in signs. Based on this fact

Comment on: "Electromagnetically induced left-handedness in optically excited four-level atomic media" [PDF]
, 2006 We discuss the recent proposal by Thommen and Mandel (Phys. Rev. Lett. {\bf 96}, 053601 (2006)) for electromagnetically induced negative refraction.
