Terahertz (THz) band is an important range in photonics, and provides numerous advantages in various applications. One of the most popular detection methods for THz pulses is electro-optic sampling (EOS). EOS provides many benefits; however, in this method distortion damages the output signal, and limits the bandwidth of this technique. In this article, a calculation-based approach is proposed to remove the effect of distortion in EOS detection process. This manner is based on definition of a base-level spectrum which modifies the output of EOS to eliminate unwanted disorders. The introduced method is computational, inexpensive, feasible, fast, adaptable, and effective. Moreover, a detailed comprehensive step-by-step model of THz time-domain spectroscopy (THz-TDS) with a simple and obvious perspective for ZnTe and GaP crystals is provided.

一种通过电光采样减少太赫兹脉冲检测失真的重建方法

太赫兹 (THz) 频段是光子学中的一个重要范围，在各种应用中具有众多优势。太赫兹脉冲最流行的检测方法之一是电光采样（EOS）。EOS 提供了很多好处；然而，在这种方法中，失真会损害输出信号，并限制该技术的带宽。在本文中，提出了一种基于计算的方法来消除 EOS 检测过程中失真的影响。这种方式基于基础级频谱的定义，该基础级频谱修改 EOS 的输出以消除不需要的紊乱。所引入的方法是计算性的、廉价的、可行的、快速的、适应性强且有效的。此外，还提供了详细、全面的太赫兹时域光谱（THz-TDS）模型，对 ZnTe 和 GaP 晶体具有简单明了的视角。
