摘　　要：报道了采用电子束直写制作计算全息图 (CGH)的新方法 ,该方法与传统的计算全息图制作方法相比可以明显提高CGH再现的像质 (信噪比和对比度 )。给出了两种制作方法的对比实验结果 ,同时就量化编码误差对CGH信噪比的影响进行了理论分析。A new method of making computer-generated hologram (CGH) by electron-beam direct writing was reported. Compared with conventional CGH fabricating method, the new method can improve the image quality of CGH obviously. The comparative experimental results of the two methods were given, and the effects of quantizing and coding errors on the signal-to-noise ratio of CGH were analyzed theoretically.
