Abstract
An imaging method and apparatus to provide digital calibration of an optical system that includes one or more removable plane parallel plates or optical wedges. One example of the method includes generating an initial estimate of an optical point spread function of an optical imaging system that includes a plane parallel plate or optical wedge positioned in the optical train based on an optical prescription of the optical imaging system, capturing a first image of a scene using the optical imaging system, and applying a blind deconvolution process to the first image using the initial estimate of the optical point spread function to produce a refined estimate of the optical point spread function and produce a second image that is substantially without blur.
