摘要
本文描述了一种基于电光采样技术和脉冲数字全息技术的单次测量自由传播太赫兹脉冲的全时空电场的方法。从捕获的数字全息图中，我们可以通过重建算法在数值上恢复完整的太赫兹电场E(x, y, t)。空间分辨率和时间分辨率分别受到探测器分辨率和探针脉冲持续时间的限制。通过数值仿真验证了该方法的有效性
Single-Shot Measurement of the Full Spatiotemporal Field of a Terahertz Pulse
In this paper, we describe a method for single-shot measurement of the full spatiotemporal electric field of a freely propagating terahertz pulse based on electro-optic (E-O) sampling technique and pulsed digital holography. From a captured digital hologram, we could numerically recover the complete THz electric field E(x, y, t) by a reconstruction algorithm. The spatial and temporal resolutions are limited by the resolution of the detector and the probe pulse duration respectively. The validity of the proposed method is verified through numerical simulation
