Paper Abstract

The paper deals with the calibration error of unequal phase changes across the interferogram in phase shifting interferometry, i.e., tilt-shift error. For its detection the lattice-site representation of phase shift angles is used. The error can be readily discerned using (N+1) algorithms. Four and five frame algorithms are considered. The influence of experimental parameters on the error detection sensitivity is discussed. Numerical studies are complemented by experimental results.
