- Abstract
Using the interferograms obtained by Mach-Zehnder interferometry, it was introduced how to use Interferometrical data evaluation algorithms (IDEA) software to realize processes of Mask, 2D Fast Fourier Transformation and Phase Unwrapping, thus phase shift distribution diagrams corresponding from the interferograms were obtained. The results show that the phase shift of the interferograms can be extracted by simple menu commands in IDEA. Meanwhile the optical noise and shadows in the interferograms can be effectively reduced. Therefore, the phase extraction based on IDEA has certain significance in the application of optical interferometry.
