Abstract:
The fiber Fabry-Perot interferometer used to measure the refractive index modulation of polymer-dispersed liquid crystal is introduced.From measuring the quantity of the interference fringe shift with a CCD based on the theory of isoclinal interference fringes formatting,the maximal refractive index modulation versus different external voltages,3.899×10-3 in the external voltage of 57.4 V/μm,and the dynamic refractive index modulation versus response time in the external voltage of 8 V/μm are found in our prepared 1.250 mm-thick PMMA/E49/TNF/ECZ polymer-dispersed liquid crystals.The experimental results will be helpful to understand the photoinduced reaction mechanism of the material and optimize the mixture ratio of each component.
