提出并实现了用一般Ｈｅ－Ｎｅ激光器记录的大景深多重全息术．这种技术是根据光源时间相干性的特点，在参考光上作光路补偿来扩大景深，并用旋转光楔调制两平面参考波，记录大景深物场的多重全息图．这是一种重像数可以选择的大景深多重全息术．文中给出理论分析和实验结果，理论分析与实验结果是吻合的．文中还提出了用旋转光楔实现多路多参考光编码记录的多通道大景深全息干涉计量术．这种技术可用于研究大景深物场的时间序列动态过程。 A large depth of field multiple holography recorded with a general He-Ne laser was proposed and implemented. This technique expands the depth of field based on the temporal coherence of the light source by compensating for the light path on the reference light and modulates the two planes of the reference wave with a rotating wedge to record the multiple holograms in the large depth of field. This is a multi-image holography with a large depth of field. The theoretical analysis and experimental results are given in this paper. The theoretical analysis is consistent with the experimental results. In this paper, a multi-channel large-depth-field holographic interferometry is also proposed to realize multi-channel multi-reference optical code recording with a rotating wedge. This technique can be used to study the time-series dynamic process of large-field depth of field.
