Unlike the Benton two-step rainbow holographic process, a new technique for making the two-step rainbow holograms is presented. Orthoscopic holographic images produced separately in both steps are used and the final reconstructed image is orthoscopio under white light illumination. Analysis indicates that the reconstructed image with matched longitudinal-lateral magnification can be obtained and furthermore, the use of converging reference waves, an major obstacle of making Benton s two-step holograms, is removed. Experimental results are included.
