Abstract

Un aparato para tomografía de coherencia óptica comprende: una fuente de luz (210); un primer brazo que incluye un primer con- junto óptico dispersivo (220, 234, 230), que induce una primera cantidad de dispersión en la luz que proviene de la fuente de luz y atraviesa el primer brazo, donde el primer brazo está configurado como uno de un brazo de muestreo y un brazo de referencia de un interferómetro; un segundo brazo que incluye un segundo conjunto óptico dispersivo (220, 244, 246, 248; 520), que induce una segunda cantidad de dispersión en la luz que proviene de la fuente de luz y que atraviesa el segundo brazo, donde el segundo brazo está configurado como el otro del brazo de muestreo y el brazo de referencia, siendo la segunda cantidad de dispersión mayor que la primera cantidad de dispersión; una unidad de procesamiento (262) configurada para procesar una señal de interferometría con el fin de realizar una tomografía de coherencia óptica de rango completo codificada por dispersión, en el que la señal dé interferometría es representativa de una superposición de la luz del primer brazo y de la luz del segundo brazo, donde para cualquier conjunto secundario de uno o más elementos ópticos del segundo conjunto óptico dispersivo, una cantidad de dispersión inducida por el conjunto secundario en la luz que atraviesa el segundo brazo es diferente de la primera cantidad de dispersión.
