ABSTRACT:
A method of forming a varying pattern of optical elements on or in at least one side of an optical panel member involves cutting or forming a pattern or patterns of cavities in a cylindrical or curved substrate or in a sleeve or sleeve segment of the substrate that corresponds to a desired pattern and shape of optical elements to be formed on or in the optical member. The substrate or sleeve or sleeve segment containing the desired pattern or patterns of optical element shaped cavities or depositions or mirror copies or inverse copies thereof is used in production tooling or as a master for production tooling to form the corresponding pattern of optical elements on or in at least the one side of the optical panel member.
