WebbTilt (optics) In optics, the term tilt is a deviation in the direction a beam of light propagates. Tilt quantizes the average slope in both the X and Y directions of a wavefront or phase … WebbA system and method are used to compensate for distortions or aberrations in an image formed in a projection system. Pattern data is generated corresponding to features to be formed on a substrate. At least one of aberrations and distortions of a projection optical system are measured. The pattern data is altered based on the measuring step.

WebbPiston and tilt are not actually true optical aberrations, as they do not represent or model curvature in the wavefront. If an otherwise perfect wavefront is "aberrated" by piston and tilt, it will still form a perfect, aberration-free image, only shifted to a different position. Defocus is the lowest order true optical aberration.
