Optical phase retardation
WebApr 15, 2024 · Phase retardation, or meridional differences in index of refraction, is an optical signature of the HFL and can be used to localize the fovea in normal and in diseased eyes , track eye position (13, 14), and quantify changes associated with normal aging and with ocular disease (10, 16). WebIntroduction to Polarization. Understanding and manipulating the polarization of light is crucial for many optical applications. Optical design frequently focuses on the wavelength and intensity of light, while neglecting its polarization. Polarization, however, is an important property of light that affects even those optical systems that do ...
