Paper Abstract

Phase shifting and logical moire (PSALM) is used to process fringes obtained by holographic interferometry. A moire is generated between the holographic pattern and a computer generated reference via logical operations. The computer grating is shifted to give the required number of shifted patterns to solve for the unknown deformation induced phase. Comparison with FFT is demonstrated.
