Reflection display of rainbow holograms
A reflection display method of rainbow holograms is discussed. A bright and sharp reconstructed image can be obtained by setting a high-reflectance metal film behind the hologram. A properly choiced bias transmittance of the hologram can lead to a diffraction efficiency close to or a little higher than that of transmission reconstruction. The distance between the metal film and the hologram should be determined carefully for a high-quality reconstructed image. Both theorectical analysis and experimental results are presented.
