提出了一种新的随机光编码技术。所提出的技术是基于两个二进制掩码：编码掩码和解码掩码。每个掩码本身是随机的，并且不包含可以解码的信息。只有当两个面具结合在一起时，解码的信息才被揭示出来。这样，灰度级以及颜色信息的编码是可能的。这种方法特别适用于安全应用。
A novel technique for random optical encoding is suggested. The proposed technique is based upon two binary masks: an encoding mask and a decoding mask. Each mask in itself is random, and contains no information that may be decoded. Only when the two masks are joined together, the decoded information is revealed. This way, the encoding of gray level as well as color information is possible. This approach is especially suitable for security applications.
