Abstract

"SISTEMA DE EXTENSAO DE AMPLITUDE E FILTRO ESPACIAL PARA OTIMIZAR IMAGENS DE HARTMANN - SHACK E MéTODOS ASSOCIADOS". A presente invenção refere-se a uma amplitude de sensor de frente de onda, que é estendida através da focalização de luz colimada em um arranjo de lentes pequenas, uma saída criando uma grade formada por extremidades das lentes pequenas e um ponto de referência nos elementos da grade. Cada ponto de referência tem uma relação conhecida com o elemento de grade e um centróide. Uma relação entre os centróides de referência é determinada. Em seguida, uma frente de onda que emana de um olho é focalizada no arranjo de lentes pequenas, com uma saída do arranjo de lentes pequenas formando a grade e pontos do olho com anomalia sobre ela, cada ponto de olho tendo um centróide. Uma relação entre os centróides de pontos de olho é determinada. Uma relação conhecida entre um centróide de referência e o centróide de um ponto de olho é identificada. Finalmente, pelo menos algumas das relações restantes entre os centróides de referência e os centróides de pontos de olho são determinadas. As relações determinadas proporcionam uma medida indicativa da anomalia do olho.
