Paper Abstract

A further development of the fiber optic hydrostatic pressure sensor with a liquid crystal film acting as a sensing element is presented. To enhance the amount of the optical signal entering the liquid crystal optrode gradient index (GRIN) rod lenses have been used in the pressure environment. The paper discusses the effect of stress induced birefringence in a GRIN lens, its influence on defocusing phenomena under pressure and the optimized configuration of the fiber optic liquid crystal sensor preset for a required range of pressure.
