摘要：

It is well known that the superposition of two identical random dot patterns may give rise to a particular form of moire effect known as a Glass pattern. Surprisingly, new research results show that if one chooses appropriate dot shapes for each of the two random dot patterns, while keeping the random dot locations in both layers identical, it is possible to synthesize in the superposition a Glass pattern having any desired shape and intensity profile.
