Birefringence vs dichroism
Webbirefringence and dichroism can also be observed in extrin-sically chiral systems. In such a system a non-chiral struc-ture together with the incident wave forms a geometrical arrangement that cannot be superimposed with its mirror im-age and thus the whole arrangement is chiral. This mecha-nism of polarization rotation was first identified ... WebWe introduce a method of azimuthally invariant 3D Mueller-matrix (MM) layer-by-layer mapping of the phase and amplitude parameters of anisotropy of the partially depolarizing layers of benign (adenoma) and malignant (carcinoma) prostate tumours.

Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive … See more A mathematical description of wave propagation in a birefringent medium is presented below. Following is a qualitative explanation of the phenomenon. Uniaxial materials The simplest type … See more While the best known source of birefringence is the entrance of light into an anisotropic crystal, it can result in otherwise See more Birefringence and other polarization-based optical effects (such as optical rotation and linear or circular dichroism) can be observed by measuring any change in the polarization of light … See more In an isotropic medium (including free space) the so-called electric displacement (D) is just proportional to the electric field (E) according to D … See more Much of the work involving polarization preceded the understanding of light as a transverse electromagnetic wave, and this has affected some terminology in use.
