远场法重现近场同轴全息图
Far Field Reconstruction of Near Field In-line Hologram
【摘要】 采用近场方式记录的同轴全息图重现时受孪生像的影响比较严重;采用远场方式记录的同轴全息图重现时几乎不受孪生像的影响.为了提高成像分辨率,人们采用近场方式记录软X射线同轴全息图.本文利用计算机实现近场全息图的远场法重现.模拟实验证实了方法的可行性.
【Abstract】 The reconstruction of near field in-line hologram is distorted seriously by the twin-image, However, the reconstruction of far field in-line hologram is much out of the distortion. In order to improve the resolution, near field hologram recording method is used in the soft X-ray in-line holography. In this paper? we use far field reconstruction method to eliminate the twin-image. Simulation results prove it practical.
