In this paper, we proposed a phase shifting Lau phase interferometry for the measurement of the focal length of a lens. The fundamentals of this application are discussed and the basis of the phase map interpretation is outlined. A three step phase-shifting algorithm is used to depict the phase maps

A method of testing the monochromatic focal length of a spherical lens by using a joint Fourier transform spectrum interference technique is proposed and experimentally demonstrated. The focal length is determined by the spacing of the interference fringes resulting from two identical input images a
