Abstract
We present the experimental data on the direct measurements of spatial distribution of the terahertz (THz) pulse intensity profile using a commercial silicon-based charge-coupled device (CCD) camera in the spectral range from 1-3 THz. A method to measure the dimensions of a high-intensity THz radiation beam in the focal plane using the CCD camera is proposed and experimentally verified.
摘要
我们展示了在1 - 3太赫兹光谱范围内，使用商用硅基电荷耦合器件（CCD）相机直接测量太赫兹（THz）脉冲强度分布空间分布的实验数据。提出了一种使用CCD相机测量焦平面上高强度太赫兹辐射光束尺寸的方法，并通过实验进行了验证。
