Abstract
An encryption-selectable holographic storage algorithm in LiNbO3 using angular multiplexing is proposed and demonstrated. It offers more flexibility to encrypt or not encrypt the data (optionally) during the recording processes. The functions encryption and nonencryption storage are alternately handled by a random-phase pattern and a uniform-phase pattern. The random phase pattern is also used to decrypt the encrypted information. The experimental results obtained using a ground glass to realize the proposed method are presented.
