By dynamical encoding of the pupil it is possible to increase image resolution when it is limited by aberrations. This technique can be applied when a photodiode array is used, providing digitized data. This encoded detection must be followed by a decoding transform. A gain in signal-to-noise ratio is obtained with regard to aperture limitation. Application to astigmatism which needs a one dimensional encoding only is presented.
