A method of fabricating a hologram having a pattern made up of pixels in
which a photosensitive material for forming a hologram is stacked on
either a reflection-type hologram or a transmission type hologram.
According to one aspect of the invention, the photosensitive material is
stacked on a reflection-type relief hologram and reconstructing
illumination light of a given wavelength is struck on the reflection-type
relief hologram through the photosensitive material, so that interference
fringes produced by interference of the light diffracted from the
reflection type relief hologram and the incident light are recorded in
the photosensitive material. According to another aspect of the
invention, the photosensitive material is stacked on a transmission-type
hologram, and reconstructing illumination light of a given wavelength is
struck on a side of the transmission type hologram that is not opposite
to the volume hologram photosensitive material, so that interference
fringes produced by interference of light diffracted from the
transmission type hologram and reference light incident on the
photosensitive material are recorded in the photosensitive material.
According to a third aspect of the invention, the photosensitive material
is stacked on a transmission type hologram, and reconstructing
illumination light of a given wavelength is struck on a side of the
transmission type hologram that is not opposite to the photosensitive
material, so that interference fringes produced by interference of light
diffracted from the transmission type hologram and zero-order transmitted
light are recorded in the photosensitive material, and a reflecting layer
is provided on a back side of the photosensitive material.
