Abstract:
A method is described for recording a volume reflection holographic image that is viewable when illuminated by light at a wavelength Wv. The method includes providing a transparent holographic recording medium having a refractive index n, said holographic recording medium being photosensitive to external light provided at a wavelength W that is different than Wv; disposing a first transparent refracting medium in contact with a first surface of the holographic recording medium; and exposing the holographic recording medium to a signal coherent light source that includes image or other information to be recorded in the holographic recording medium and a reference coherent light source, the signal coherent light source and reference coherent light source emitting light at the wavelength W and entering the holographic recording medium through opposing surfaces thereof, wherein the signal coherent light source or the reference coherent light source passes through the first transparent refracting medium before entering the holographic recording medium at an internal angle of incidence greater than arcsin(1/n).
