Abstract
APARELHO DE INTERFERÊNCIA àTICA. Um aparelho de interferência ótica para realizar tomografia de coerência ótica de domínio Fourier incluindo meio para prover múltiplos feixes pelo que interferogramas sào gravados simultaneamente para uma pluralidade de diferentes profundidades focais dentro de uma substância a ser examinada, cada interferograma sendo provido por um dos múltiplos feixes. Sào providos meios para combinar imagens derivadas a partir dos interferogramas para uma pluralidade de diferentes profundidades focais, pelo que uma única imagem pode ser construída com uma profundidade de campo aumentada. O espaçamento axial dos focos é calculado para considerar a faixa Rayleigh da cintura focal na substância a ser examinada.
