Surface Control of LC Alignment for Creation of Liquid Crystal Lenses Arrays

Abstract

New photosensitive alignment materials, capable to obtain pretilt angle from 90 to 0 degree in single technological process of UV exposure, are developed. The novel technological method for fabrication LC lens and LC lenses arrays has been developed based on new pretilt angle gradient alignment materials. Laboratory samples of voltage tunable LC lens and LC lenses arrays are obtained and characterized. The developed low cost fabrication technology of tunable micro-lenses arrays based on photosensitive alignment materials has low complexity and is perspective for light field technology applications.
