Abstract:
A polarization-independent liquid crystal micro-lens array, comprising, an optically transparent, dielectric planar panel, an optically transparent upper planar electrode deposited upon the planar panel top surface and bottom surface, a top substrate positioned adjacent to the planar panel top surface, a top pattern electrode deposited on the top substrate internal surface, a top liquid crystal layer disposed between the planar panel top surface and the top substrate internal surface, the top liquid crystal layer having a first polarization, a bottom substrate positioned adjacent to the planar panel bottom surface, a bottom pattern electrode deposited on the bottom substrate internal surface, a bottom liquid crystal layer disposed between the planar panel bottom surface and the bottom substrate internal surface, the bottom liquid crystal layer having a second polarization orthogonal to the first polarization.
