Abstract :
A two-dimensional measurement technique based on the electro-optical Kerr effect for electrical field distribution in dielectric liquids is described. The optic phase distribution of light is modulated in square pulsed mode by optical and electric modulations respectively. To decrease the effect of the noise component resulting from the electro-hydro-dynamic motion of the dielectric liquid, a diagnostic image lock-in amplifier technique is proposed
