Abstract
Numerical simulations of the influence the phase step miscalibration and average intensity differentiation between the frames on the calculated interferogram contrast using the temporal phase shifting method (TPS) are presented. The fringe function includes in its argument the amplitude of vibration studied by the time-average method. Some features of the TPS method known from the interferogram phase calculations are confirmed and properties characteristic to contrast determination are established. Experimental studies of vibration resonant mode patterns of silicone microelements provide corroboration of theoretical and numerical findings.
