【Abstract】 A method of how to generate a deformation digital moire Fringe pattern with carrier fringeand to analyze its phase is introduced. The digital moire Fringe pattern generated by a digital imagegrabbing system can show the whole field of object deformation directly. A high quality of full-field ofphase map can be accurately obtained by using a new method, a relative Fourier transformunmudulating technique in frequency field. The experimental results well fitting with the theoretic ones arepresented.更多还原
