Abstract
La invención se refiere a un procedimiento para leer un holograma (7) grabado en un medio de almacenamiento holográfico (6) con un sistema de almacenamiento holográfico (1). El procedimiento comprende las etapas de: calcular un valor característico a partir de una imagen detectada de un holograma de Fourier reconstruido en al menos dos posiciones relativas de un haz de referencia (3) y dicho medio de almacenamiento (6), siendo cada uno de los valores característicos indicativo de una desalineación del haz de referencia (3) y dicho medio de almacenamiento (6) en la posición relativa respectiva, calcular un valor de servo a partir de los valores característicos medidos, determinar una posición relativa alineada de dicho haz de referencia (3) y dicho medio de almacenamiento (6) por medio de una función de servo predeterminada que usa el valor de servo calculado, establecer la posición relativa del haz de referencia (3) y dicho medio de almacenamiento (6) en dicha posición relativa alineada, y detectar una imagen en dicha posición relativa alineada. La invención también se refiere a un sistema de almacenamiento holográfico (1) para leer un holograma de Fourier (7) grabado en un medio de almacenamiento holográfico (6), comprendiendo dicho sistema (1) medios generadores del haz de referencia (3), medios receptores del medio de almacenamiento (6) y un detector (5) para detectar un holograma reconstruido. El sistema (1) además comprende una unidad de control de servo (14) para ejecutar el procedimiento según la invención.
