Abstract

The paper describes a new type of optical element, combining the properties of the deflector and the lens. The idea of the new element is to change electrooptically the wave front of light the same way as the classical lens does. In other words, the new lens will focus the light like usual lens. The simplest construction of variable focus lens is almost identical to prism-type deflector except but parabolic profile of slit between the upper electrodes. Changing the electrical voltage, connected to the two half of parabolically cut electrode, on will change the point of focusing, so the focus distance of such lens will be electrically changed. The evaluation shows that volume type of variable focus lens can be realized with modern high effective electrooptical materials. Much more effective operating such lens can be realized in waveguide variant.
