Abstract

Liquid crystal (LC) lens with voltage and azimuth dependent focus is realized by using divided electrode structure. By applying appropriate potentials on the divided electrode, the LC cell behaves like an optical lens having astigmatic properties; the phase retardation of an incident light beam takes an elliptical shape in the cross-section. The axes of the elliptical shape of the phase retardation are electrically controllable.
