A chiral ferroelectric smectic C* liquid crystal (FLC) with the helix pitch p 0 = 330 nm was developed to avoid any scattering of visible light when the helix is not unwound over a certain limit. Planar cells with different FLC layer thickness (16 an

In order to study the relation between the ohmic resistance measured in a thin conducting ribbon and the length of a transversal cut, we employ a one-parameter deformed exponential and logarithm that were recently introduced (Phys. Rev. E 66 (2002) 0

Direct measurement of the two principal refractive indexes of a nematic liquid crystal slab

Autor: Claudio Oldano, Taverna Valabrega Piera, L. Trossi, Elio Miraldi

Publikováno v: Applied optics. 21(22)

A new technique to measure the principal refractive indexes of a nematic liquid crystal is presented. The method is based on an indirect measurement of the refraction angle by determining the direction of a magnetic field which minimizes the light sc
