  • Optically based voltage sensing device and method
    Patent number: 9921248
    Abstract: A method of measuring fluctuations in electric fields is disclosed, the method comprising the step of: placing a Liquid Crystal Device in communication with the electric field, the device having disparate orthogonal polarization sensitivity to an external electric field; utilizing an optical probe beam having a known polarization state to interrogate the liquid crystal of the liquid crystal device to produce a response beam; and analyzing the polarization state of the response beam to provide an indicator of the corresponding fluctuations in the electric field.
    Type: Grant
    Filed: January 25, 2013
    Date of Patent: March 20, 2018
    Assignee: ZEDELEF PTY LTD
    Inventors: Zourab Brodzeli, Leonardo Silvestri, Andrew Mark Michie, Vladimir Chigrinov, Eugene Pozhidaev, Francois Ladouceur

  • Device and method for the temperature-independent operation of electro-optical switches on the basis of ferroelectric liquid crystals having a deformed helix
    Patent number: 6900874
    Abstract: In order to substantially reduce temperature-dependent influences and attendant long switching times in the case of an optical liquid crystal modulator having at least one ferroelectric liquid crystal and in a method for operating an optical liquid crystal modulator, the ferroelectric liquid crystals are provided to have a DHF mode and to exhibit an operating range of an electric field of more than 20 V/?m at the location of the liquid crystal.
