The Tilt of Excitement

The Tilt of Excitement (ToE) is a deviation in the direction a beam of light propagates. The ToE quantizes the average slope in both the X and Y directions of a wavefront or phase profile across the pupil of an optical system. In conjunction with piston (the first Zernike polynomial term), X and Y ToE can be modeled using the second and third Zernike polynomials.
