Abstract
Un sistema para grabar un holograma redundante de un objeto sobre un área determinada de un medio de grabación con una referencia mutualmente coherente y haces de información de energía de onda de una longitud de onda determinada lambda, cuyo sistema comprende elementos de iluminación que incluyen una disposición de agujeros minúsculos en relación espaciada con el objeto para iluminar el objeto a través de la disposición de agujeros minúsculos con energía de onda coherente de una longitud de onda determinada lambda, para proporcionar el haz de información caracterizado en que la disposición tiene agujeros minúsculos sustancialmente idénticos dispuestos en un patrón periódico predeterminado con un mínimo de espaciamiento d entre cualquier par de agujeros minúsculos adyacentes, y cada uno de cuyos agujeros minúsculos tienen una dimensión máxima a, y la relación entre d/a es de cuando menos 30.
