An optical wavefront sensing system includes a lenslet array positioned f or receiving an incoming wavefront. Downstream of the lenslet array is position ed an image transformer, which transforms the image emerging from the lenslet arra y at a focal plane thereof into a real image. A sensor is positioned at a final ima ge plane for sensing the transformed image. This sensor may comprise, but not intended to be limited to, a charge-coupled-device (CCD) camera. The method for sensing an optical wavefront includes the steps of receiving an incoming wavefront usin g a lenslet array and transforming an image emerging from the lenslet array at a focal plane thereof into a real image. The transformed image positioned at a final image plane is then sensed, and, in a preferred embodiment, analyzed to determine wavefront distortions.
