Use Wavefront Extend the Depth-of-Field of the Iris Capture System
利用波阵面扩大虹膜采集装置的景深

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.
