Title

Entire Spectrum Measurement Of Kerr Constant And Birefringence Dispersion In A Polymer-Stabilized Blue-Phase Liquid Crystal Composite

Abstract

A new method is proposed and implemented experimentally for measuring the electric-field induced birefringence together with the Kerr constant of a polymer-stabilized blue-phase liquid crystal (PSBPLC) composite. The conventional Senarmont compensation method is only suitable for the single wavelength measurement limited by the achromatic zero order quarter wavelength plate (QWP). In our new method, the QWP is removed so that a broad band light source can be used instead of monochromatic incident light. Herein planar ITO electrodes are employed, producing a uniformly distributed vertical electric field. Thus the fitting data is accurate and convincing prior to that from the IPS cell measurement. By rotating the sample to an oblique angle and using the spectrometer to scan the voltage dependent optical transmission, the induced birefringence and the Kerr constant for the entire visible spectrum can be carried out using the single band model. Quantitative experimental results have been obtained and presented in this paper to support this proposed scheme. © 2013 Society for Information Display.
