To resolve phase estimation errors in standard sinusoid fitting caused by assumptions of invariant phase and fixed sample rates per fringe.
Derived an error formula quantifying phase inaccuracies in standard sinusoid fitting when phase varies or sampling rates deviate.
Developed a modified sinusoid fitting (MSF) algorithm accommodating linear phase variation across fringes independent of sample density.
Compared standard and modified sinusoid fitting algorithms on phase reconstructions in noiseless and noisy conditions.
Mathematical modeling identified predictable phase calculation errors when conventional sinusoid fitting assumptions are violated.
Modified sinusoid fitting accurately reconstructed phase distributions across varying fringe sample rates in both noisy and noiseless scenarios.
