The present paper is invested in studying the measurement of birefringence as a function of
the temperature for weakly polar nematic liquid crystals (NLC) doped with magnetic …

We present a new mathematical technique which can be used to determine the main
refractive indices and the birefringence of an anisotropic layer by using a polarizing …

An interferential method is used for determining the linear birefringence of the thin polymer
foils. The channeled spectra of anisotropic polyethylene terephthalate (PET) transparent …

The birefringence of MBBA, determined from the channeled spectra, decreases when the
wavelength increases, showing a normal dispersion. The changes induced by an external …

The proposed method of channeled spectrum employs the recorded channeled spectrum of
an optical active polymer solution placed between two crossed polarizers. The approach …

The mutual influence of two mesogenic components, namely a nematic liquid crystal N-(p-
methoxy-bezylidene)-butylaniline (MBBA) and a lyotropic liquid crystal poly-(phenyl …

The visible rotatory birefringence of glucose solution is about [1.3–2.75] 10-6 and the
dispersive parameter varies in the range [1.8–3.0] 10-8. The specific rotation of aqueous …

A simple method for determining the linear birefringence of the transparent uniaxial
anisotropic layers is described in this manuscript. Linear birefringence is a dispersive …

Lyot-Ohmann tuneable filters obtained from liquid crystalline layers for visible range are
modelled by changing the intensity of an external electrostatic electric field applied to the …
