Abstract 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.
