我们成功地利用飞秒脉冲激光全息术实现了飞行光的数字记录。我们记录并重建了飞秒光脉冲在印有测试图的扩散板上传播的运动图像。锁模钛宝石激光器被用作飞秒脉冲激光器。光脉冲的中心波长和持续时间分别为800 nm和96 fs。我们进行了数值模拟，以验证所提出的技术。我们证实了该技术能够记录飞秒光脉冲传输的运动图像。此外，我们实验证明了该技术，并成功地观察到飞秒光脉冲传输为576 fs。实验结果与仿真结果吻合较好。
We succeeded in digital light-in-flight recording by holography by use of a femtosecond pulsed laser. We recorded and reconstructed a moving picture of femtosecond light pulse propagation on a diffuser plate on which a test chart pattern was printed. A mode-locked Ti:sapphire laser was used as a femtosecond pulsed laser. The center wavelength and the duration of the light pulse were 800 nm and 96 fs, respectively. We conducted a numerical simulation in order to validate the proposed technique. We confirmed that the technique was capable of recording the moving picture of femtosecond light pulse propagation. In addition, we experimentally demonstrated the technique and successfully observed femtosecond light pulse propagation for 576 fs. The experimental results agreed well with the simulation results.
