Abstract :
Our paper describes a new type of optical deflector, based on the breaking of the total internal reflection by the transference of isotropic insulating liquid in capillary by meaning of ponderomotive force, acting on liquid in the electric field. Theoretical modeling of liquid flow process in capillary, driven by ponderomotive force, has been done. The using results of this modeling, theoretical dependencies of switching time on driving voltage, liquid permittivity and viscosity, liquid container surface wettability and device dimensions has been obtained. Experimental investigation of the device response time on driving voltage for number of liquids with different permittivity and viscosity has been made. Experimental results are in good agreement with theoretical conclusions
