Rainbow holography using a large aperture lens for a full object beam.
A method of making rainbow holograms by using a full object beam is described. In this technique we simultaneously use a moving object and a moving imaging lens, instead of using a slit during the exposure process. The position of the synthetic slit is independent of the position of the imaging lens and its focal length. Using this method, a one-step rainbow holographic image with a large visual field and high resolution can be obtained. A theoretical analysis and some experimental results are presented.
