Abstract: (933 Views)
In this paper electro-optical properties of focal length tunable lens with modal structure were investigated. Modal structure governing equations include modal layer electrical potential distribution and liquid crystal director angle distributions in the cell. These equations were written by finite difference and finite element method in MATLAB environment. Optical path length of cell with E7 liquid crystal and modal structure were examined with different electrical voltages and surface resistances. In frequency of 1 kHz, minimum focal length of lens was obtained in electrical voltage of 2.9 volt and surface resistance of 125 MΩ⁄sq.
