Previous studies have shown-that the intensity of the correlation peaks in Vander Lugt optical correlators can change with the position of the object because of emulsion thickness effects. In this paper, it is shown that the intensity variations are caused by a combination of thickness effects and a position-dependent frequency cutoff due to space variance of the optical processor. Experiments showing the global effect, as well as experiments showing each effect acting alone, have been performed.
先前的研究表明，由于乳胶厚度效应，范德卢格特光学相关器中相关峰的强度会随物体位置而变化。本文表明，强度变化是由厚度效应以及光学处理器空间方差导致的位置相关频率截止的综合作用引起的。已经进行了展示整体效应的实验，以及展示每种效应单独作用的实验。
