Temperature effect on liquid crystal refractive indices
نویسندگان
چکیده
A model describing the temperature effect of liquid crystal ~LC! refractive indices is derived and confirmed by experiment. Two single LC compounds ~5CB, 5PCH! and two mixtures ~MLC-6241-000 and UCF-35! with different birefringence values were used to validate the model. This model fits all the experimental data well. For a low-birefringence LC mixture, if the operating temperature is far below its clearing point, the temperature-dependent refractive indices can be approximated as a parabolic form. This prediction is also experimentally validated. In addition, a linear relationship between ^n& and temperature is found. © 2004 American Institute of Physics. @DOI: 10.1063/1.1757034#

Calculation of Optical Parameters of Liquid Crystals
Validation of a modified four-parameter model describing temperature effect on liquid crystal refractive indices is being reported in the present article. This model is based upon the Vuks equation. Experimental data of ordinary and extraordinary refractive indices for two liquid crystal samples MLC-9200-000 and MLC-6608 are used to validate the above-mentioned theoretical model. Using these ex...
متن کاملFabrication and characterization of Mach–Zehnder interferometer based on a hollow optical fiber filled with radial-aligned liquid crystal
We demonstrate a high sensitivity allfiber Mach–Zehnder interferometer (MZI) based on radialaligned liquid crystal (LC) in a hollow optical fiber (HOF). The transmission spectrum of the liquid crystalfilled fiber MZI (LCFMZI) was measured at different temperatures, and the thermalinduced wavelength shift of the interference spectrum probed. The experimental results indicate that the LC ali...
متن کاملRefractive index measurements at a 2nd order smectic A to C phase transition
2014 A measurement of the 3 principal refractive indices of azoxy-4,4’ (di-undecyl 03B1-methyl cinnamate) is made in the vicinity of the 2nd order smectic-A to smectic-C phase transition. The experimental procedure is : first the index differences are measured using the conoscopic method, then the absolute value of one of the indices is determined using an Abbe refractometer. In the smectic-A p...
متن کاملRefractive Indices, Order Parameter and Optical Transmittance Studies of a Nematic Liquid Crystal Mixture
Measurements of ordinary refractive index, birefringence, density, and order parameter were made on a technologically important nematogen and the data obtained for its nematic and isotropic phase were reported. A modified wedge method was used for the measurement of the birefringence (δn). The nematic–isotropic phase transition temperature matches very well as is exhibited from the value of ref...
متن کاملModeling of Refractive Indices for Binary Aqueous Solutions of Some Alkane Polyols at Constant Temperature and Pressure
In this research, a theoretical study has been undertaken on the density and also on the relationship between refractive index and density for aqueous solutions. A simple linear equation is suggested to show this relationship. Also, a semi-empirical equation has been developed for estimating the constant of this linear equation. By using our suggested equations, the refractive indices of aq...
