  • Title: Utilizing critical angles in sensing partially ordered liquid crystal profile.
    Author: Abu-Abed AS, Lindquist RG.
    Journal: Opt Express; 2009 Dec 21; 17(26):23729-35. PubMed ID: 20052084.
    Abstract:
    This paper investigates a new approach for tracking nematic uniaxial liquid crystal (LC) profile in partially ordered LC based sensors. This approach utilizes measuring critical angles for total internal reflection (TIR) at the interface of optically isotropic and partially ordered LC film. The proposed optical transduction requires measuring of the ordinary critical angle and two extraordinary critical angles in orthogonal directions to report the LC degree of ordering and the director axis orientation.
