Effect of batch thermal-fixing on multiple holograms in Fe:LiNbO_3

摘要

We have investigated the characteristics of thermal fixing holograms in batch. The loss of signal-to-noise ratio (LSNR) is used in comparing the noise performance of hologram before and after each batch of thermal fixing. The experiment results on batch fixing show that the deterioration in hologram fidelity is mainly caused in recording phase at the room temperature, and the repeated fixing processes won't further produce significant noise to degrade holograms.
