Electrically Controlled Liquid Crystal Twist-Planar Fresnel Lens
Abstract
Based on the method of photo-orientation of azo dye AtA-2, an electrically controllable Fresnel lens has been developed, representing a microstructured liquid crystal element with alternating rings with twist- and planar orientations of the liquid crystal director. It is shown that the use of the control voltage allows one to control the efficiency of laser radiation focusing, as well as to turn off the lens. The optimum value of the control voltage (~3 V) is determined, at which the maximum focusing efficiency and satisfactory quality of imaging in a wide spectral range from 530 nm to 1.1 μm are achieved.
