SOFAST computes high-resolution maps of optical slope across a mirror surface. These data sets show example SOFAST calculations, beginning with projected fringes (or fixed-pattern artwork), and showing results of intermediate calculation steps up to final analysis results. The data sets include both images and machine-readable stored information.
First example posted, but we plan to include more details, and more example cases
