The experimental search of the shape of electrical voltage is presented for controlling the optical phase modulator based on dual frequency nematic liquid crystal. Two basic approaches were tested. One is based on universal relation between two driving frequencies, below and above inversion point, respectively. Another approach uses the combination of pulses of both frequencies, which allow us, at first, to provide the fast transition between chosen retardations and , at second, to hold final retardation for the necessary duration.
