Abstract
Provided is a systemic approach to creating a hologram from a sequential series of two dimensional transparencies each having a differing viewpoint of a scene taken simultaneously by a camera in incoherent light and a projection apparatus using coherent light in combination with said transparencies to form a rainbow hologram of the scene originally photographed. The invention utilizes a lenticular lens array to provide parallax information and a perpendicularly oriented cylindrical lens for focusing, along with additional optical enhancing elements, to obtain high quality rainbow holograms from scenes originally photographed in natural light.
