Abstract
Large image reconstruction using a factor of 5 smaller hologram is realized with an optical system which consists of two Fresnel lenses and one common lens. The secondary Fresnel lens also serves as a projection screen. Furthermore, using the same optical system, a true color hologram is achieved by using three primary color lasers. Reconstruction is by the same lasers or white light. The stringent requirement for the optics is discussed.
