Abstract
A novel concept for the compensation of aberrated images has been developed. It is based on the idea of introducing a pupil mask that blocks the most highly tilted portions of the incoming wavefront. Such a mask might consist of a spatial light modulator. The SLM would be driven by a binary Hartmann sensor. Subapertures with low tilt would turn on their corresponding SLM pixels allowing the nearly flat portions of the wavefront to propagate. Subapertures with larger tilts would act to turn off their SLM pixels, eliminating those portions of the pupil that don not contribute to the core of the image.
