Compensation of the Birefringence of a Polymer by a Birefringent Crystal

Science, 2003
We report a method for compensating the birefringence of optical polymers by doping them with inorganic birefringent crystals. In this method, an inorganic birefringent material is chosen that has the opposite birefringence to that of the polymer and has rod-shaped crystals that are oriented when the polymer chains are oriented.

Birefringence of actin

Biopolymers, 1991
AbstractThe total strain birefringence of F‐actin isolated from chicken gizzards was measured as a function of elongation in thin transparent films. Each film held at a certain elongation in a jig was allowed to swell in a penetrating but nondissolving liquid. Seven liquids with different refractive indices were employed.

Reversibility of photoinduced birefringence in ultralow-birefringence fibers

Optics Letters, 1996
New measurements of the birefringence induced in ultralow-birefringence fibers by a succession of orthogonally polarized UV side exposures show the reversibility of the process. Moreover, it is shown that the birefringence growth depends on two parameters, the total irradiation dose and the nature of the successive polarized UV side exposures.

Studies of the birefringence and birefringence dispersion of polypeptides and proteins

Biopolymers, 1966
AbstractAn apparatus has been constructed which permits the polarimetric observation of streaming solutions of macromolecules. The apparatus is a streaming birefringence device allowing the usual measurements of birefringence parallel to the cylinder axis but which in addition transmits light in the radial direction.

Birefringence of muscle proteins and the problem of structural birefringence

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1968
Abstract 1. 1.|The birefringences of the muscle proteins actin and myosin were determined and compared with data on other fibrous proteins. 2. 2.|The specific birefringence Δn sp = Δn/f v c is the birefringences per unit volume fraction of a parallel array of rod-like molecules.
