Reflection display of rainbow holograms.
In this paper experimental results and a detailed analysis of a method for reflection display of rainbow holograms are presented. A method for noncontact reflection display is put forward. High quality reconstructed images can be obtained by simply placing a mirror at a proper distance behind the holograms. Essential requirements are derived to avoid interference fringes and unacceptable image blur. The diffraction efficiency which may be close to or even higher than that of transmission display in some conditions is also discussed. Experimental results are presented which fully coincide with the analysis.
