Abstract

In our earlier work, a group of error-compensating phase shifting algorithms with known phase step of (pi) /2 has been derived, and the optimal phase steps for Carre algorithm and Stoilov-Dragostinov algorithm were determined and a good and recommended choice is also (pi) /2. This paper gives a further evidence of error compensating merits of these algorithms. Theoretical analysis, as well as computer simulation is given for evaluating the phase errors due to the most common error sources, such as linear and quadric phase shifter errors, quadric detector error and additive random error.
