Light-in-flight (LIF) recording by holography is a powerful technique for observing ultrashort light pulse propagation. However, the recordable time of the technique has been limited by the lateral length of the holographic plate. Then, to extend the recordable time of LIF recording by holography, we proposed a space-division multiplexing technique of holograms, which divides the holographic plate longitudinally and uses double reference light pulses. We experimentally demonstrated that the recordable time becomes twice as long as before for the first time, to the best of our knowledge, using the proposed technique. Specifically, we recorded the motion picture of the ultrashort light pulse propagation for 236 ps.
利用全息术进行光飞行（LIF）记录是一种观察超短光脉冲传播的强大技术。然而，该技术的可记录时间一直受到全息板横向长度的限制。为了延长全息术 LIF 记录的可记录时间，我们提出了一种全息图的空间复用技术，该技术将全息板纵向分割并使用双参考光脉冲。据我们所知，我们首次通过实验证明，使用该技术，可记录时间延长了一倍。具体来说，我们记录了超短光脉冲传播的运动图像，记录时间为 236ps。
