Abstract

One-time phase shifting method, by which a high-quality correlation fringe image has been obtained, is presented in this paper. By comparison with the image quality obtained in traditional ways through simulation on a computer, there is no essential difference between images obtained by this method and twice or three times π/2 phase shifting methods. Subsequently, the image obtained from experiments of digital shearography is processed. Experiment result proves that the method is feasible.
