摘　　要：采用一种新的数字全息再现方法,将电荷耦合器件CCD与电寻址液晶EALCD相结合实现数字全息的再现.同时将数字图像处理技术与数字全息术相结合,应用MATLAB软件对记录的全息图进行数字图像处理,实验结果表明,该方法简单快速.通过图像增强等方法对全息图进行数字图像处理,在全息再现中,全息干涉图的对比度得到了显著的提高,有利于全息干涉条纹的自动判读.A new method of digital holography that combines the charge-coupled device（CCD） with the electrically addressed liquid crystal display（EALCD） is introduced.The recorded hologram is processed with MATLAB by digital image processing technology.The results show that the method is simple.In the holographic reconstruction process,the contrast of holographic interferogram is significantly increased by digital image enhancement method,which is helpful for the automatic recognition of the holographic interference fringes.
