Properties of New Fluorinated Holographic Recording Material for Collinear Holography

A new fluorinated holographic recording material is applied with a view to realizing holographic information system (HIS) media that offer high multiplexing numbers and high recording sensitivity. We report here, for the first time, the successful recording and reconstruction of 750 multiplexed holograms on a 50 ×50 mm2 photopolymer coupon sample based on a novel fluorinated holographic recording material for collinear holography. The proposed material yields bit error rates (BERs) less than 10-2 in the X–Y plane of the coupon sample and thus is suitable for 532 nm optical data storage. Its fundamental properties, such as the relationship between BER and number of holograms, are determined. This new fluorinated material offers improved error maps as evidenced by the 0.4-mm-thick, 120-mm-diameter photopolymer disc. The average error rate is 1.61% for the disc sample. This new material successfully stored and reproduced a short segment of animated video data.
