WebApr 12, 2024 · The distortion correction is the key step for accurate coordinate system transformation. Two types of distortions exist when imaging a tube-like specimen by OCT. One is the distortion induced by the difference between the lateral and axial resolutions, the other is the distortion induced by the curved surface and the changes of the refractive ... WebMay 17, 2024 · Eye stroke is caused when the flow of blood to the back of the eye is impaired, starving tissues of oxygen. In the same way a stroke causes cell death in the brain due to the lack of oxygen, an eye stroke can destroy tissues of the retina or optic nerve, thus preventing the transmission of nerve signals to the brain.
WebJun 12, 2024 · Optical distortion is distinct from perspective distortion, which is where different lenses with different focal lengths give different fields of view and display … WebSep 12, 2024 · Example \(\PageIndex{1}\): Maximum supportable data rate in multimode fiber optic cable. Solution; Light may follow a variety of paths through a fiber optic cable. Each of the paths has a different length, leading to a phenomenon known as dispersion. Dispersion distorts signals and limits the data rate of digital signals sent over fiber optic ...
WebOptics is the branch of physics which involves the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light.
