Single-shot quantitative birefringence microscopy for imaging birefringence parameters
Optics Letters, 2019A method for realizing 2D single-shot measurements of birefringence parameters (including both retardation and optic axis orientation) of anisotropic materials using a simple recording setup and an efficient processing algorithm is proposed. The recording setup can be built simply by inserting a circular polarizer and a polarization beam splitter ...

IT has been known for some time that the cell membrane of an amœba in water is birefringent. The optical axis lies radially, and the sign is positive with respect to the tangent1 (Fig. 1). I have found that if an Amœba proteus is fixed for about 10 min.

Narrow band mirrors composed of a polarizer, a stack of lossless birefringent crystals, and a conventional mirror are described. Curves showing the reflectance characteristics of the mirrors are included. Design data are tabulated for narrow band mirrors that have appreciable between-peak reflectances because of the Gibbs phenomenon as well as for ...

In recent years it has become common for the birefringence pattern of a thermally toughened glass lens to be examined, and for a judgmental opinion of the impact resistance of that lens to be based on the regularity of the observed pattern. Laboratory experiments were carried out to determine the validity of this practice.

Wavelength dependence of birefringence in highly birefringent fibers
Optics Letters, 1982A simple technique is used to measure the wavelength dependence of the birefringence in highly birefringent fibers. In stress-induced fibers, the stress and shape birefringences reinforce each other, whereas in elliptical-core fibers the stress and shape birefringences can either reinforce each other or partially cancel, depending on the wavelength.
