Liquid-crystal micro-lens array with two-divided and tetragonally hole-patterned electrodes.
We propose a liquid crystal (LC) micro-lens array with the structure of two-divided and tetragonally hole-patterned electrodes. Each LC cell in the lens array behaves like cylindrical or spherical lens properties by electrically adjusting the applied voltages. The LC micro-lens array is useful for tuning optical properties such a focal length and deflection angle of a light emitting diode (LED) illumination system.
