摘要
近年来太赫兹技术因其重要的理论研究价值和广泛的应用前景引起了科学界的普遍关注。 太赫兹光谱技术作为太赫兹科学发展的主要方向之一, 可分为频域光谱与时域光谱两种。 它的出现解决了太赫兹波段下无法产生宽带辐射源的难题, 使得光谱学上存在的太赫兹断层得以填补。 随着这项技术的发展, 对太赫兹波段下物质特性的研究也逐步拓展到生物医学、 材料、 通信、 安检为代表的各个领域。 从产生原理、 性能特点、 应用领域等方面对两种光谱进行比较, 进而阐述了两种太赫兹光谱的优缺点以及其应用优势。
Abstract
In recent years, terahertz wave has attracted much attention and interest from the scientific community because of its important theoretical research value and broad application prospects. Terahertz spectroscopy is one of the main directions of terahertz scientific development, which is divided into two types: frequency domain spectrum and time domain spectrum. Its appearance has solved the problem of producing broadband radiation source in terahertz band, and made the terahertz fault in spectroscopy to be filled. With the development of this technology, the research about the radiation characteristics of terahertz has been gradually extended to the biomedicine, materials science, communication science, security inspection fields and so on. This paper compares the two kinds of spectrum from the production principle, performance characteristics and application ,and it introduces in detail the advantages and disadvantages as well as the superiority in some research fields of two kinds of terahertz spectrum.
