Abstract
The generation theory of interference fringes patterns considering the aberration of the focusing lens is proposed in a position-sensing grating interferometer for a specular object. The proposed theory is based on the assumption that the deformation of the wavefront passing the interferometer is limited by the symmetry of the interferometer and that the wavefront can be expressed by Zernike polynomials. The simulation and experimental results are presented. The interference fringes pattern of the form of a barrel and a spool were obtained by the simulation. The experimental results agreed well with the simulation results.
