3. We are calling this method “SOPS” (“Spot-Optimized Phase Stepping” Interferometry)
An order of magnitude reduction!

4. We call our improved method “AMPS” (“Area-Mapped Phase-Shift” Interferometry)
“A faster method for in-situ wavefront correction using area-mapped phase-shift interferometry,” G. Hall, G.C. Spalding, P.J. Campagnola, J.G. White, K. W. Eliceiri
