Abstract:
A holographic image film, and a holographic image recording method and reconstruction method are provided. The holographic image recording method includes a preparation step, an irradiation step and a recording step. The preparation step includes stacking a holographic negative film on a transparent substrate. The irradiation step includes emitting object light and reference light. The reference light is emitted into the transparent substrate and undergoes multiple times of total reflections in a thickness of the transparent substrate to form total internal reflected light. The recording step includes generating a holographic image interference line by a mutual interference between the total internal reflected light and the object light, and recording the holographic image interference line on the holographic negative film in a photosensitive manner.
