Abstract

Se proporciona un sistema (OCTI2 - OCT12") para ópticamente medir dimensiones internas de un objeto muestra (10), por ejemplo un ojo (20), dicho objeto comprende interfaces internas (14, 14', 14") en las que cambia el índice de refracción de forma que una porción de la luz incidente es retroreflejada y/o retrodispersada y se puede detectar, por medio de tomografía de coherencia óptica (OCT), comprende por lo menos un primer dispositivo de OCT (OCTI) adaptado para medir dimensiones internas en un primer volumen parcial (17) del objeto (10), caracterizado por una combinación con por lo menos un segundo dispositivo de QCT (OCT2) adaptado para medir dimensiones internas en un segundo volumen parcial (19) del mismo objeto (10), en donde el segundo volumen parcial (19) es por lo menos parcialmente diferente del primer volumen parcial (17); El primer y segundo dispositivos de OCT (OCT1, OCT2) pueden compartir por lo menos de forma parcial y espacial primer y segundo brazos de muestra superpuestos (SA1, SA2), los cuales pueden tener respectivas y diferentes longitudes focales (fi, f2) y pasan a través de un sistema de lente óptico común (L12) hacia el objeto, y los cuales pueden compartir una fuente de luz común (LSI2); las dimensiones internas en un primer volumen parcial (17) del objeto y dimensiones internas en un segundo volumen parcial (19) del mismo objeto (10) se miden por medio de tomografía de coherencia óptica (OCT) en una solo operación de medición, pero con diferente resolución espacial.
