提出了一种利用散斑抑制技术提高数字全息再现像质量的方法。散斑的大小和位置根据波长而改变以记录数字全息图。通过将不同波长的再现像叠加，减小了散斑的影响，从而提高了像质。光学实验证实了所提出的方法。(c)2008年美国光学学会
A method to improve the image quality of a digital holographic reconstructed image by means of speckle reduction is proposed. The size and position of the speckles are changed according to the wavelengths to record a digital hologram. By superposing reconstructed images with different wavelengths, the effect of speckle is reduced so that the image quality is improved. Optical experiments are given to confirm the proposed method.
