Abstract

método e dispositivo para produzir padrões de cor por meio de redes de difração. a presente invenção refere-se a um método para criar padrões de cor para aplicações técnicas e visíveis ao olho humano por meio de redes de difração através da irradiação de luz, os arranjos de rede de difração que são produzidos diretamente em uma superfície de corpo sólido em um processo de microestruturação a laser através de pelo menos uma instalação de laser na faixa de nanossegundo ou na faixa de pico ou femtossegundo, sendo que cada arranjo de rede de difração é composto de subáreas (81) cuja dimensão longitudinal tem um valor abaixo da habilidade de resolução do olho e que contém pelo menos um pixel (81,82,83) sendo que um pixel é uma estrutura de rede de difração limitada para produzir uma cor espectral. a aplicação direta de tais estruturas de rede de difração de produção de cor em uma superfície de corpo sólido possibilita uma grande variedade de possibilidades decorativas e de autenticação que variam de ferramentas de gofragem até joias.
