Abstract :
Wavefront coding[1] is the most commonly used method of extending the depth of field (DOF). In this method, the DOF is extended by phase modulation of the pupil function using a cubic phase mask and digital processing using a deconvolution filter. We propose a new aperture for the system that extends the DOF and suppresses artifacts.
