Abstract
A method to characterize interference fringes is proposed by utilizing a Fresnel zone plate. Through the optical power measurement of the far-field irradiance produced by an image grating and a Fresnel zone plate, the interference fringe periods are obtained. This scheme can be used for a wide range of fringe periods, and may enable achievement of subnanometer fringe characterization with corrected error sources.
