中文摘要：

该文针对虹膜识别系统中虹膜采集装置采集虹膜图像很不灵活的问题，给出一种利用加波阵面来延长景深的方法。文中详细分析了其可行性及设计方法，并给出了运用此系统采集虹膜，进行虹膜识别的比较实验结果。该方法对虹膜识别的推广具有很高的参考价值。

英文摘要：

The procedure of captured iris requires considerable cooperation from the user. The method using wavefront to extend the depth-of-field of the image capture system is expatiated in the paper, The feasibility and method of realization are given in detail. Finally, the result of iris recognition contrast experimentation using this system is introduced. The method has high value for popularizing iris recognition.
