Abstract
Aparato de interferencia óptica para llevar a cabo una tomografía de coherencia óptica de dominio de Fourier que incluye medios (13) para proporcionar múltiples haces (14, 15, 16, 17), con lo que simultáneamente se registran interferogramas para una pluralidad de diferentes profundidades focales dentro de una sustancia que va a examinarse (33), proporcionándose cada interferograma por uno de los múltiples haces (14, 15, 16, 17), y estando configurada una sonda para pasar la pluralidad de haces a la sustancia que va a examinarse a la pluralidad de diferentes profundidades focales, y en el que los medios para proporcionar múltiples haces (13) comprenden medios (45) para recibir un haz único (11) y medios para dividir el haz único (11) en dichos múltiples haces (14, 15, 16, 17), caracterizado porque los medios para generar múltiples haces comprenden una superficie reflectante (43) y una superficie parcialmente reflectante (47), con lo que un haz recibido pasa a la superficie parcialmente reflectante (47) y una proporción del haz pasa a través de la superficie parcialmente reflectante (47) para formar un primer haz (14) y otra proporción se refleja a la superficie reflectante (43), en la que se refleja de vuelta a la superficie parcialmente reflectante (47) y una proporción del haz pasa a través de la superficie parcialmente reflectante (47) para formar un segundo haz (15), estando dispuestas la superficie parcialmente reflectante (47) y la superficie reflectante (43) de modo que los haces primero (14) y segundo (15) se desplazan en paralelo entre sí, proporcionándose haces sucesivos adicionales(16, 17) de los múltiples haces (14, 15, 16, 17) por reflexiones y transmisiones en la superficie reflectante (43) y la superficie parcialmente reflectante (47).
