An Iterative Tilt-Immune Phase-Shifting Algorithm

Your library or personal account may give you access

Abstract

An iterative least-squares-based phase-shifting algorithm was developed to cope with random pistons and tilts from the phase shifter. The allowable tilt amount was 0.5 waves over the pupil. The achieved rms accuracy was 0.0024 radians.
