Abstract:	An encryption-selectable holographic storage algorithm in LiNbO3 using angular multiplexing is proposed and demonstrated. It offers more flexibility to encrypt the data or not optionally during the recording processes. The function of encryption and non-encryption storage is switched by a random phase pattern and a uniform phase pattern. The random phase pattern is also used to decrypt the encrypted information. Experimental results using a ground glass in support of the proposed idea are presented. 我們提出並展示了一個可擇式光學保密儲存的體積全像記憶體。此記憶體在記錄過程中提供了加密與否的選擇性，而加密與否的功能則是經由亂數相位的光罩與均勻相位光罩彼此的切換來達成；此外，亂數相位光罩亦是解密過程的鑰匙。我們利用毛玻璃實現了此一構想，實驗結果與理論構想相吻合。
