摘　　要：提出并实现了高通滤波法重现同轴全息图，消除孪生象的影响。详细解释了这种方法的原理。通过数字模拟。In this paper, high pass filter method is proposed and realized to eliminate the twin image in the reconstruction of in line hologram. The principle is explained in detail. Digital simulation result shows that the reconstructed image of the in line hologram with high pass filter method is free from the distortion of the twin image.
