The cylindrical holographic stereogram, invented by Lloyd Cross, is one of the most significant developments of the last decade in commercial holography. This hologram has several technical problems, however, which have limited its application in the commercial marketplace. Two of these problems are its limited vertical viewing range and rainbow colored rather than natural colored images. This paper reviews the general problem of color holography and discusses the specific requirements for generating color images in Cross holograms. Several optical techniques are described, and experimental results obtained with one especially promising technique are presented.
