Observing light propagation plays an important role in clarifying ultrafast phenomena occurring on femtosecond to picosecond time scales. In particular, observing the ultrafast behavior of polarized light is useful for various fields. We have developed a technique based on Polarization Light-in-Flight Holography, which can record light propagation as a motion picture that can provide information about the polarization direction. Here we demonstrate motion-picture recording of a phenomenon, which is characteristic of polarized light, by using the proposed technique. As a phenomenon, we adopted the behavior of a light pulse incident at Brewster's angle. We succeeded in recording the light reflection of specific polarized light by the proposed optical setup. The method of recording the motion-picture, reconstruction procedure, and the quantitative evaluation of the results are demonstrated.
观察光的传播对于阐明在飞秒到皮秒时间尺度上发生的超快现象起着重要作用。特别是，观察偏振光的超快行为在各个领域都很有用。我们开发了一种基于飞行中偏振光全息术的技术，它可以将光的传播记录为一部能提供偏振方向信息的动态影片。在此，我们通过使用所提出的技术展示了对一种偏振光特有的现象进行动态影片记录。作为一种现象，我们采用了以布儒斯特角入射的光脉冲的行为。我们成功地通过所提出的光学装置记录了特定偏振光的光反射。展示了动态影片记录方法、重建过程以及结果的定量评估。
