title: La biréfringence électriquement contrôlée dans les cristaux liquides nématiques.
abstract: This work reports the effects of a pulsed voltage on the field alignment of a nematic liquid crystal that is initially homeotropic. This excitation presents the same effect as a continuously applied voltage of amplitude V if a relation between the height of the pulses and the amplitude V is satisfied. The application of a magnetic field perpendicularly to the cell increases the threshold voltage and decreases the response time of the nematic.
