Abstract

"SENSOR DE FRENTE DE ONDA COM ILUMINAçãO FORA DO EIXO". Aberrações de frente de onda em um olho são detectadas com a iluminação da retina, com o recebimento da luz refletida pela retina e com o uso de um detector Hartmann-Shack (112) ou semelhante para detectar as aberrações. A luz de iluminação (102) é aplicada ao olho do eixo óptico do olho (A). A luz refletida a partir da córnea e a luz refletida a partir da retina percorrem em diferentes direções. A primeira pode ser bloqueada com um diafragma (108), enquanto que a última é passada para o detector.
BRPI0014924-1A 1999-10-21 2000-10-20 processo e sistema para iluminar a retina de um olho, e processo e sistema para determinar uma aberraÇço de frente de onda de um elemento àptico. BR0014924B1 (pt)
