将一个匹配空间滤波器(MSF)和全息光学元件(HOE)结合在一个单层底板上,得到一个紧凑的光学频率平面相关器。给出图样识别相关实验数据,并对此系统的位移不变性进行了已得到实验证实的理论分析。
Combining a Matched Spatial Filter (MSF) and a Holographic Optical Element (HOE) onto a single-layer backplane yields a compact optical frequency plane correlator. The experimental data of pattern recognition are given, and the theoretical analysis of the displacement invariance of the system has been verified by experiments.
