Paper Abstract

Based on image theory under incoherent illumination, the requirements of focus and distance between two gratings are discussed for the Lau effect under incoherent illumination by means of a divergent beam. The relationship between the pitch of the Lau fringes and the geometric parameters of the optical system is also discussed. Our conclusion expands former achievements. The experimental results agree with those of the theory.
