By tilting both the input and the image planes of a holographic system and adopting a diverging reference wave for hologram recording, a special type of multiplex hologram can be produced in one-step. Due to symmetry of reconstruction geometry, the reconstructed 3D image from this type of rainbow hologram can be viewed by the surrounding observers simultaneously. Theoretical formulation for the holographic process is presented. Some numerical simulation and experimental result demonstrating the characteristics of the reconstructed image are included.
