【摘要】 本文讨论计算全息图,侧重制作Lohmann全息图.编制并计算了拉格朗日内插傅里叶二元全息图的程序,对Lohmann全息图位相误差进行了修正,提高了再现质量,使计算全息图的应用推进了一步.更多还原

【Abstract】 Computer holograms, Lohmann holograms in particular, are discussed in this paper. Lagrangiun iuterapolated binary Fourier holograms of two dimensions are programmed and computed, and modification of the phase errors of Lohmann holograms is made. It improves the reconstructed image quality and pushes forward the applications of computer holograms.更多还原
