ABSTRACT:
A wide-angle zoom lens with as few as two plastic elements codes the wavefront produced by the imaging system such that the imaging system is substantially invariant to aberrations related to misfocus. Signal processing is used to decode the wavefront to form the final image. A first type of zoom lens configuration uses as few as two lens elements. In this type, image processing may be modified to take into account the positioning of the lenses.
