Abstract

sistema e método para medir opticamente as dimensões internas de um objeto um sistema (oct12 - oct12"<sym>) é provido para medir opticamente as dimensões internas de um objeto de amostra (10), por exemplo, um olho (20), dito objeto incluindo interfaces internas (14, 14', 14") ás quais o índice de refração muda de forma que uma porção de luiz incidente seja refletida de volta e/ou espalhada de volta e possa ser detectada, por meio de tomografia de coerência óptica (oct), incluindo pelo menos um primeiro dispositivo de oct (oct1) adaptado para medir as dimensões internas em um primeiro volume parcial (17) do objeto (10), caracterizado por uma combinação com pelo menos um segundo dispositivo de oct (oct2) adaptado para medir as dimensões internas em um segundo volume parcial (19) do mesmo objeto (10), em que o segundo volume parcial (19) é pelo menos parcialmente diferente do primeiro volume parcial (17). o primeiro e segundo dispositivo de oct (oct1, oct2) podem compartilhar pelo menos parcialmente sobreposto espacialmente primeiro e segundos braços de amostra (sa1, sa2), que podem ter comprimentos focais diferentes respectivos (f1, f2) e passam por um sistema de lente óptico comum (l12) para o objeto, e que podem compartilhar uma fonte luminosa comum (ls12). dimensões internas em um primeiro volume parcial (17) do objeto e dimensões internas em um segundo volume parcial (19) do mesmo objeto (10) são medidas por meio de tomografia de coerência óptica (oct) em uma única operação de medição, mas com resolução espacial diferente.
