太赫兹产生技术的不断发展催生了太赫兹非线性光谱学、极端太赫兹强场与物质相互作用等前沿学科.由此,围绕发展强场太赫兹时域光谱测量技术需具备单次测量能力和大动态范围两个特点,介绍强太赫兹时域光谱测量技术的研究进展,分析这些技术的优缺点及今后的发展趋势.

With the rapid development of terahertz(THz)generation technology, the front subjects such as terahertz nonlinear spectroscopy, the interaction between extreme terahertz intense field and matter have emerged. Therefore, the development of the intense terahertz time-domain spectroscopy technology has become one of the most important requirements in terahertz technology. The technology needs to have the characteristics of single-shot measurement ability and large dynamic range. This paper reviews the research progress and presents some comments on the features and the trend of intense terahertz time-domain detection.
