The imaging performance of high resolution airborne Synthetic Aperture Radar (SAR) system can be affected by phase errors resulted from the change in refractive index in the troposphere. Using the ...
A novel fiber sensor based on surface plasmon resonance (SPR) is designed to realize the simultaneous measurement of temperature and refractive index (RI). In order to obtain the SPR effect both in x- ...
A new study introduces a diffractive optical framework for real-time 3D and multispectral imaging, eliminating digital reconstruction and mechanical scanning through deep-learning-optimized PSF ...
In patients who previously underwent refractive surgery or corneal inlay implantation, the small-aperture IC-8 Apthera IOL ...
Dry eye is very common, especially post corneal refractive surgery, and should be treated preoperatively with attention paid ...
This meant that a microscope could not resolve two objects located closer than λ /2NA, where λ is the wavelength of light and NA is the numerical aperture of the imaging lens.
Laser direct writing functional optical materials enable high-resolution and optically thin computer-generated holograms with a wide range of applications. However, the traditional material system ...
This paper reports on the news about refractive index measurements and spectroscopic features of thin films, which can be applied as optical planar waveguides, focusing on their manufacturing ...
CONCLUSIONS The degree of transient hyperopia associated with rapid correction of hyperglycaemia is highly dependent on the rate of reduction of the plasma glucose level. A reduction of refractive ...
