Abstract: Systems and methods include optics having one or more phase modifying elements that modify wavefront phase to introduce image attributes into an optical image. A detector converts the optical image to electronic data while maintaining the image attributes. A signal processor subdivides the electronic data into one or more data sets, classifies the data sets, and independently processes the data sets to form processed electronic data. The processing may optionally be nonlinear. Other imaging systems and methods include optics having one or more phase modifying elements that modify wavefront phase to form an optical image. A detector generates electronic data having one or more image attributes that are dependent on characteristics of the phase modifying elements and/or the detector. A signal processor subdivides the electronic data into one or more data sets, classifies the data sets and independently processes the data sets to form processed electronic data.

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.
