Rainbow holography of 3-D diffuse objects with HOE/MEHL.
A new technique of one-step rainbow holography with a multiexposure holographic lens (MEHL) is described. The synthesization of the slitlike function in the object wave can be performed with the specially fabricated holographic lens. The MEHL can also be applied to the oriented speckle encoding of images in white-light optical image processing. Successful experimental results are presented.
