摘要：
A transmission hologram allowing an illuminating light source for holographic reconstruction to be placed behind the hologram, i.e. on the side opposite to the viewing side, and permitting reconstruction of an image that is bright and clear and has low chromatic dispersion, which is the feature of the reflection type volume hologram. A transmissively viewable reflection hologram has a semitransparent reflecting mirror or a semitransparent reflecting layer placed at either side of a reflection type volume hologram member. The semitransparent reflecting mirror or the semitransparent reflecting layer is integral with or separate from the reflection type volume hologram member.
