离轴数字全息图再现的一些实际考虑

Off-axis digital hologram reconstruction: some practical considerations

Nicolas Verrier, Michael Atlan

摘要:

讨论了离轴强度数字全息图的全息再现。一些主要的数值处理方法的审查,无论是基于傅立叶变换解释的传播积分或其线性系统对应的报告。本文介绍了几种常用的离轴全息图数字化处理方法,如可调放大率再现法和菲涅耳分解法。实验参数对经典的全息图再现方法的影响进行了评估,提供有关全息图记录条件的最佳图像渲染的指导方针。

英文摘要:

Holographic rendering of off-axis intensity digital holograms is discussed. A review of some of the main numerical processing methods, based either on the Fourier transform interpretation of the propagation integral or on its linear system counterpart, is reported. Less common methods such as adjustable magnification reconstruction schemes and Fresnelet decomposition are presented and applied to the digital treatment of off-axis holograms. The influence of experimental parameters on the classical hologram reconstruction methods is assessed, offering guidelines for optimal image rendering regarding the hologram recording conditions.
