BRainbow holography
Normally, a conventional transmission hologram of a 3D object which is recorded using a particular wavelength λ1 can be reconstructed and viewed using another light of wavelength λ2. But, as we described in the section holographic magnifications(section 1.1.3) the position and magnifications varies with the wavelength of reconstructed beam. In this case therefore white light can not be used for reconstruction except for certain type of recording medium like photopolymers which is a recent development in holographic recording medium. In order to make holographic stickers or to use in advertisements for viewing in white light a technique called rainbow holography is used. Rainbow holograms are recorded using monochromatic light ...
