| 摘 要： | 本文提出了一种用干涉及滤波技术实现图像相减的简单方法。将两相减图像放在透镜的前面,在平行光照射下,在透镜的后焦面上得到两图像的傅氏谱的干涉,通过适当的滤波,可滤去图像的相同部分,从而在输出得到它们的相减。

| Abstract: | This paper presents a new method of complex amplitude subtraction. The lens forms the Fourier transform spectra of two transparencies, Young's interference fringes formed by the identical image of the two transparencies are filtered with slit. The differential image of the two transparencies is obtained on the output plane. |
