Zone Plate Interferometer for Testing the Spherical Surfaces

Design and investigation of fraction Fresnel zone plate

第二届仪器科学与技术国际学术研讨会

作者： Voldemar P.Koronkevich Galina A.Lenkova Aleksey E.Matochkin Institute of Automation and Electrometry Siberian Branch of Russian Academy of Sciences Institute of Automation and Electrometry Siberian Branch of Russian Academy of Sciences Institute of Automation and Electrometry Siberian Branch of Russian Academy of Sciences

＜正＞ A diffraction interferometer with a Fresnel zone plate （hologram） situated on the center of curvature of a concave mirror was created to test the shape of the surface of spherical and parabolic mirrors. Conditions of minimizing the instrumental error of the scheme to ＜ e/20 are determined. Methods for suppression of noise and destructive interference patterns are found. Metrological tests of the interferometer were carried out;they substantiated its suitability for tests in working conditions.

Chinese Journal of Lasers 1993年第2期 23-28页

作者： Wenmin Shi, Chongxiu Yu, Pin Long, Dahsing Hsu(Beijing University of Posts & Telecommunications,Sub-Box 163, BUPT, Beijing 100088, China)

In this paper we proposes a new concept of annular-focus zone lens and its design procedure based on binary optics. An investigation of the diffraction efficiencies and the transverse intensity distributions on the focal plane of the designed annular-focus zone lenses is presented. This special kind of zone lens may be used to increase the intensities of Durnin’s diffraction-free beams.
