Abstract
The invention provides a hologram-recording subject plate comprising a block and a variety of subjects fixedly contained therein, which ensures easy, stable yet continuous recording of a multiplicity of identical holograms or different holograms reconstructible by illuminating light, , a hologram-making method using the same, and a hologram-recorded article. The subject plate comprises a transparent solid block and a hologram-recording subject contained therein. A photosensitive material film is applied directly onto one surface of the subject plate, and the subject plate is then irradiated with laser light through the photosensitive material film. Such simple operation enables a multiplicity of identical holograms to be recorded in an easy, stable yet continuous manner.
