    摘要: A tamper-evident label includes two parts that are separated from each other when an article to which they are attached is opened. The two parts have matching surface relief patterns secured to each other at an interface, and the indexes of refraction of the parts are substantially equal such that the patterns have no optical effect when attached to each other. When the two parts are separated, however, the patterns generate an image drawing attention to their separation. The patterns are preferably holographic.
