This research proposes a method that uses a single object beam to record multiple images in a photorefractive crystal medium without having to use any reference wave. The object beam in this study is modulated using a lenticular lens array sheet to produce a set of sub-object beams. These beams are then angularly separated on the recording plane and their scattered waves overlapped in an iron-doped photorefractive LiNbO₃ crystal. This single-exposure, multiple-holographic-recording method is simple and proven successful via the experiments that recorded four holograms in a 30 x 1 mm³ LiNbO₃:Fe crystal with single exposure.
本研究提出了一种方法，该方法利用单个物光束在光折变晶体介质中记录多幅图像，而无需使用任何参考波。在本研究中，物光束通过一个柱面透镜阵列片进行调制，以产生一组子物光束。然后这些光束在记录平面上进行角度分离，并且它们的散射波在掺铁光折变铌酸锂晶体中重叠。这种单次曝光、多重全息记录方法很简单，并且通过在一块30×1立方毫米的铌酸锂:铁晶体中单次曝光记录四个全息图的实验证明是成功的。
