Abstract

Wavefront Coded imaging systems are jointly optimized optical and digital imaging systems that can increase the performance and/or reduce the cost of modern imaging systems by reducing the effects of aberrations. Aberrations that can be controlled through Wavefront Coding include misfocus, astigmatism, field curvature, chromatic aberration, temperature related misfocus, and assembly related misfocus. The design and simulation of these systems are based on a model that describes all of the important aspects of the optics, detector, and digital processing being used. These models allow theoretical calculation of ideal MTFs and signal processing related parameters for new systems. These parameters are explored for extended depth of field, field curvature, and temperature related misfocus effects.
