Abstract

In this Letter, polymer-stabilized liquid crystals with experimentally observed large electro-optic effect are introduced to the electro-optical detection to improve the voltage sensitivity. The Kerr constant of materials prepared in this study reached as high as 7.2×109m/V2, increasing by 1000 times the sensitivity of the conventional electro-optical materials. The noncontact detection configuration, using a laser beam as a probe, enables quick two-dimensional scanning measurements.
