25 April 2006Optical holographic encrypted data storage using lenticular lens array phase-encoded multiplexing
We propose a novel optical holographic encrypted data storage scheme based on phase encoding multiplexed scheme. In the proposed data storage scheme, patterns of encrypted images are stored holographically in a photorefractive LiNbO3:Fe crystal by using lenticular lens array (LLA) sheet phase-encoded multiplexing.
Experimental results show that rotating a LLA placed as a phase modulator in the path of the reference beam provides a simple yet effective method of increasing the holographic storage capabilities of the crystal. Combining this rotational multiplexing with two-axis tilting multiplexing offers not only further data storage
capabilities but also data encryption possibilities.
