Abstract
An iris image capture device includes an optical arrangement that utilizes Wavefront Coding phase modifications to produce an optical image of a user iris and a detector for detecting the optical iris image and for converting the optical iris image into an electronic data signal. The iris image capture device also includes an image processor configured for processing the electronic data signal from the detector to reverse the Wavefront Coding phase modifications and to produce an electronic iris image of the user iris.
