The first proposed invisibility cloaks required materials that are highly anisotropic, spatially inhomogeneous, and that possess a magnetic response. These properties are still difficult or impractical to achieve in practice, leading many r...
Importance of individual differences in cone spectral sensitivities and color matching functions and how to correct for them: tutorial [0.03%]
个体差异对视锥光谱敏感度和颜色匹配函数的重要性及其校正方法：教程

Propagation of an orbital angular momentum beam-the Laguerre-Gaussian (LG) beam-through anisotropic non-Kolmogorov atmospheric turbulence is analyzed using three approaches: the extended Huygens-Fresnel (EHF) principle, the perturbation met...
Manipulation of the energy flow field in Bessel-Gaussian beams by polarization [0.03%]

Based on vector diffraction theory, this paper investigates the energy flow distribution and its variation characteristics of Bessel-Gaussian beams under polarization modulation. The results demonstrate that on the focal plane, the transver...
Adding personalized wavefront correction to a scleral lens after lens manufacture [0.03%]
个性化波前像差校正后巩膜镜的定制
Evan S Elam,Nasim Maddah,Alexander W Schill et al.
Evan S Elam et al.
All past demonstrations of wavefront-guided scleral lenses have relied on the full-surface method (FSM) of lens manufacture, which requires the wavefront correction to be integrated into the design of a traditional scleral lens prior to len...
Analytical one-dimensional phase gratings in scalar diffraction theory [0.03%]
一维相位光栅的解析解及其在标量衍射理论中的应用
Andrew Ducharme,Kyle Cole,Devon Ball et al.
Andrew Ducharme et al.
Diffraction gratings are a commonplace optical tool which split an incident beam into distinct diffraction orders via the far-field interference of light. However, using scalar diffraction theory to model a phase grating with phase profile ...

Hao Lin et al.
Based on pseudo-modal expansions of partially coherent beams, an analytical expression for the cross-spectral density function of pseudo-Schell model beams through an ABCD optical system is derived. The intensity distributions calculated us...
Optical quality and anisotropy across the retina of Chinese children's eyes [0.03%]
中国儿童眼睛视网膜光学质量及各向异性的区域性差异
Simon Winter,Chang Liu,Zhenghua Lin et al.
Simon Winter et al.
The goal of this study was to characterize the retinal image quality across the retina, in individual children, as a function of wavelength. The wavefront aberrations of 30 Chinese children (ages 12.8±1.8yrs) were measured with a custom-de...
