  • Abstract
    Development of a new fiber-optic method of hydrostatic pressure measurement based on pressure-induced deformations in twisted nematic liquid crystal cells is presented. The method, particularly suitable for pressures up to 2 MPa and utilizing strong rotatory power occurring in chiral nematic liquid crystals, offers high response to pressure with reduced temperature sensitivity.
