Abstract

"ACOPLAMENTO DE LUZ DE UMA FONTE DE LUZ PEQUENA PARA SISTEMAS DE PROJEçãO USANDO REFLETORES PARABóLICOS". Uma porção de um primeiro parabolóide coleta e concentra luz randomizada de uma lâmpada em feixes paralelo dirigidos para uma porção de um segundo parabolóide que refocaliza a luz em um homogeneizador. O segundo parabolóide tem uma forma que é substancialmente similar ao refletor do primeiro parabolóide. A fonte e o alvo estão localizados nos respectivos focos dos parabolóides de modo que o fluxo ótico da fonte forma imagem para o alvo com distorção mínima em um sistema de formação de imagem aproximadamente sem ampliação. O sistema pode ser configurado para controlar comprimento de onda e intensidade através da inserção de um filtro adicional. Além disso, um retro-refletor pode ser adicionado para aumentar a densidade de fluxo global no homogeneizador. A saída é particularmente adequada para fornecimento de luz ao motor de luz de projetores.
