【摘要】 介绍了一种自聚焦型计算全息的匹配滤波器。它通过对物体的共轭傅里叶谱加二次位相因子后编码、缩微而成。由于它具有自聚焦的功能,从而可以使光路大为简化,调节方便,适用于不同缩放比的物。给出了与理论一致的实验结果更多还原

【Abstract】 A new type matching filter by computer generated hologram is presented in this paper. The filter is obtained by adding quadratic phase factors into conjugate frequency spectrum of object, then encoding and reducing. Because of the filter having function of self focusing the optical configuration becomes more simple, more compact, and easier to adjust. It is suitable for objects with different scale. The experimental results are consistent with theoretic analysis provided.更多还原
