An atmospheric aberration sensor that uses two optically correlated images of a scene and the Fourier transform capabilities of a lens or other focusing element. The sensor receives light via an f-number matching element from a scene or from an external optical system and transmits it through a focusing optical element to an updateable display element such as a spatial light modulator or micro mirror array, which modulates the real time image from the focusing element with previous template image of the same extended scene.
