Transmission hologram fabrication process |
摘要 |
The invention relates to a process capable of fabricating a variety of transmission holograms having a simple structure, a wide visible range and a large area and comprising the first stage of recording the wavefront to be finally reconstructed in the form of the first hologram that is a reflection hologram with a wide visible range, the second stage of using the first hologram to record the second hologram that is a combined reflection and transmission hologram, and the third stage of recording in the third hologram photosensitive material only a transmission hologram for reconstructing only the wavefront recorded in the second hologram and desired to be reconstructed.
