摘要:
A function of two independent variables can be regarded as an image. Using a novel optical technique, the autocorrelation coefficient of such a function is formed as another image. The working principle of the instrument is based on geometrical optics alone, however, the basic equipment was further improved by adopting electronic scanning techniques. Test plates with prescribed autocorrelation functions were made, the equipment was experimentally tested, and was found to operate to satisfaction.
