Abstract

Random optical field i.e. speckle pattern of light, has been extensively investigated for various applications. Recently, it becomes generally known that the random optical field is appropriate for reference beam of holographic recording with spatial multiplexing. There are several methods to implement random optical field. Ground glass, multimode fiber, random binary mask etc., are used to implement random optical field. However these conventional methods can give only arbitrary randomness to light but cannot allow specific randomness. In this paper, we propose a design method of diffractive optical element for generating random optical field with specifically designed randomness that is applicable to hologram multiplexing system.
