Abstract

"ACOPLAMENTO DE LUZ DE UMA FONTE DE LUZ PARA UM ALVO USANDO REFLETORES ELIPSOIDAIS DUPLOS". Um sistema ótico de coleta e condensação inclui um primeiro refletor e um segundo refletor. O primeiro e o segundo refletores incluem uma porção de um elipsóide de revolução tendo dois pontos focais e um eixo ótico. Uma fonte de radiação eletromagnética é colocada em um dos pontos focais do primeiro refletor para produzir radiação que converge no segundo ponto focal do primeiro refletor. Os segundos pontos focais dos refletores coincidem. O segundo refletor é posicionado para receber a radiação depois que ela passa através de um segundo ponto focal do segundo refletor e focalizar a radiação em direção a um alvo posicionado no primeiro ponto focal do segundo refletor. Para obter iluminação máxima no alvo, o primeiro e o segundo refletores são substancialmente do mesmo tamanho e forma e posicionados em simetria ótica com relação um ao outro, de modo que a radiação refletida de uma porção de superfície do primeiro refletor elipsoidal é, em seguida, refletida de uma porção de superfície correspondente do segundo refletor elipsoidal para obter uma ampliação unitária entre a fonte e sua imagem focalizada. Os refletores elipsoidais podem incluir porções não elipsoidais ou podem ser aproximados por refletores esféricos.
