If the system in question is a message in a series of digital bits encoded in the polarisation of light, this means that intercepting and reading the message can no longer be done surreptitiously.
如果所提到的系统是用偏振光的形式，以一连串数字比特流编码来表示信息的话，就意味着截取并阅读信息没法再偷偷摸摸地进行了。
The response, which took the form of chemical reactions in the leaves, continued in the dark, showing that the plant's "memory" recalled the information encoded in light.
并且，这种光化学反应在黑暗中同样可以继续，这说明植物能够“记住”光照的信息。
A novel system based on digital color-encoded structure light for 3-D lip-moving shape measurement was presented. The principle of color-encoded 3-D shape measurement was introduced.
提出了基于数字彩色结构光投影的动态三维测量轮廓术，用于人在讲话过程中嘴唇的三维测量。
