【Abstract】 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.更多还原
