Abstract
We propose a liquid crystal (LC) micro-lens array with two-divided and hexagonal-hole-patterned electrodes for varying a focal length and a beam deflection angle. The possibilities of lens-like refractive index distributions in the hexagonal region of the LC micro-lens array are discussed. We investigate the optical properties such as the focal length and beam deflection of the micro-lens array by measuring the refractive index distributions and the transmitted light intensity distributions.
