摘　　要：在数字全息图的制取过程中,高相干性的激光会在全息图上产生斑点状的噪声,从而在再现像中产生散斑噪声,影响了全息图的质量。目前Lee滤波作为一种去除散斑噪声的方法,对全息图再现像中的乘性散斑噪声也有较好的去除效果。本文在Lee滤波的基础上,结合均值滤波,提出了加权型增强Lee滤波算法。这种方法对数字全息图再现像进行处理,获得了更好的去噪效果.In the preparation of digital holograms,a high coherence laser generates noise blotchy on the hologram,thereby generating the speckle noise in the reconstructed image and affecting the quality of the hologram.As a classic method to remove speckle noise,at present,Lee filter also has good removal effect on multiplicative speckle noise in the reconstructed image of hologram.In this paper,a weighted enhanced Lee filter algorithrn is proposed on the basis of Lee filter and mean value filter.In this method,the reconstructed image of the digital hologram is processed to obtain better denoising effect.
