| 摘 要： | 本文分析了纯相位匹配滤波实现特征识别的物理原因。据此我们修改了待识别物体的傅里叶变换的振幅,以减小光强度的动态范围。同时,保持其傅里叶变换的相位不变。用重铬酸盐明胶记录反射式全息匹配滤波器,从而获得高效率的相关检测。

| Abstract: | The physical justification of pattern recognition with a phaseonly match filter is analysed in this paper. In the experiment the amplitude of Fourier transform of object is modified to reduce the intensity dynamic range, while phase information is preserved. The holographic match filter was made by dichromatic gelation. The high emeiency correlation is obtained by using this method. |
