Enhancement of Birefringence in Reduced Graphene Oxide Doped Liquid Crystal
Nanomaterials, 2020 We investigated the effect of reduced graphene oxide (rGO) doping on the birefringence of 5CB liquid crystal (LC). The characteristics of the synthesized rGO and LC-rGO composite with different rGO concentrations were analyzed by atomic force microscopy,

Imaging polarimetry for the determination of stress constraint in transparent solids
EPJ Web of Conferences, 2010 Using a Mueller matrix polarimeter based on liquid crystal cells [1] and the forward polar decomposition [2], we study the evolution of the birefringence property induced by an increasing compression of a Plexiglas sample.

Long-Time Relaxation of Stress-Induced Birefringence of Microcrystalline Alkali Halide Crystals
Molecules, 2018 Alkali halide single crystals are most commonly used as the diluent matrix in the tablet method or disk technique for spectroscopic measurements. However, stress-induced birefringence (SIB) of alkali halides as well as intrinsic birefringence manifest ...
