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。

According to the principle of rotating prism multiplex holography and great depth holography, a multiplex holography with great depth by using He-Ne laser is demostrated. The technique uses reference beam path compensation and rotating prism modulation of two plane reference beams to record multiplex hologram of great depth of object field. The multiplexing number could be chosen arbitrarily. The theoretical analysis and experimental results are presented and shown well in agreement. A multiplexing technique is proposed for holographic interferometry of great depth which uses multiple reference beams to enode and record holograms. This technique can be used for observing time sequencing dynamical process of great depth of object field.
