In this Letter, a pulsed digital holographic approach for detecting the three-dimensional (3D) field distribution of a freely propagating single terahertz (THz) pulse based on an electro-optic (E-O) sampling technique is proposed, by which the 3D field distribution of a single THz pulse sampled at different time points can be recorded in real-time on a series of subholograms and will be finally reconstructed as a series of two-dimensional spatial electric field distributions in a time series with a time resolution of femtosecond order. Simulation is carried out to demonstrate the process of the implementation, which confirmed the feasibility of the proposal.
在这封信件中，提出了一种基于电光（E-O）采样技术的用于探测自由传播的单个太赫兹（THz）脉冲的三维（3D）场分布的脉冲数字全息方法，通过该方法，可以实时记录在不同时间点采样的单个 THz 脉冲的 3D 场分布在一系列子全息图上，并最终以飞秒级时间分辨率的时间序列中的一系列二维空间电场分布来重建。进行了模拟以演示实施过程，这证实了该建议的可行性。
