Abstract

Substrato óptico e método de produção. A invenção apresenta um substrato de superfície óptica. O substrato óptico apresenta uma superfície tridimensional. O substrato óptico é definido por uma primeira função de estrutura da superfície modulada por uma segunda função de estrutura da superfície, a primeira função de estrutura da superfície produzindo ao menos um componente especular a partir de um primeiro feixe de luz incidente. A segunda função de estrutura da superfície apresenta uma geometria com pelo menos características pseudo-aleatórias para modular a primeira função de estrutura de superfície de tal forma que a superfície do substrato óptico produz a luz especular e difusa a partir de um feixe de luz incidente, O substrato óptico é apropriado para uso em diversas aplicações, incluindo os dispositivos de aumento de brilho e de projeção.
