Abstract

Phase-shifting is a well-known technique for phase retrieval that requires a series of intensity measurements with certain phase-steps. Additive noise is one of the most important source of errors in interferometry. In this work we present a systematic algebraic approach for the generation of self-tunable phase shifting algorithms that minimize the propagation of additive noise.
