Birefringence imaging
Birefringence is formally defined as the double refraction of light in a transparent, molecularly ordered material, which is manifested by the existence of orientation-dependent differences in refractive index. Many transparent solids are optically isotropic, meaning that the index of refraction is … See more The simplest crystalline lattice structure is cubic, as illustrated by the molecular model of sodium chloride in Figure 1(a), an arrangement where all of the sodium and chloride ions are … See more where e is a variable representing the dielectric constant, and n is the material's measured refractive index. This equation was derived for specific frequencies of light and ignores dispersion of polychromatic light … See more Anisotropic crystals, such as quartz, calcite, and tourmaline, have crystallographically distinct axes and interact with light by … See more Electromagnetic radiation propagates through space with oscillating electric and magnetic field vectors alternating in sinusoidal patterns … See more WebIn recent years we have developed rapid technologies that detect the location of the fovea using retinal birefringence scanning (RBS). Yet, combining it with ophthalmic imaging technologies is not trivial, mainly because RBS employs polarized light and polarization-sensitive optics, while most ophthalmic imaging systems do not.
