High-speed and -accuracy measurement of optical rotation by liquid crystal modulators

Abstract

Optical characteristics of material that has optical activity have been used for the concentration measurement of the saccharide and amino acid for a long time. Some principal of optical rotation measurement techniques have been proposed by a rotating polarizer method, a Farady cell method. A high-speed and high-accuracy measurement of optical rotation is proposed by dual liquid crystal polarized modulators which are specialized multi-stacked cells with over-drive method for high speed drive.
