叙述了获得分形图像的一种光学方法。这种方法是通过对光学傅氏变换所获得的一系列初始图像进行卷积。如果所有的图像具有相同的傅里叶光谱特征，而这些光谱却具有着不同的尺度，在输出平面上便可获得分形图像。实验表明，用这种方法可在光学上产生简单的规则分形图像。
An optical method for obtaining fractal images is described. This method is based on a series of initial images obtained by optical Fourier transform. If all the images have the same Fourier spectral characteristics and the spectra have different scales, a fractal image can be obtained on the output plane. Experiments show that using this method can produce simple regular fractal images optically.
