Development of a Waveguide-Coupled Broadband Terahertz Spectrometer

在化学研究仪器和设备-仪器开发(CRIF-ID)计划的支持下，莱斯大学电气和计算机工程系的Daniel M.Mittleman将开发一种太赫兹光谱仪，它将把时域光谱的许多有用功能与商业FTIR系统的易用性和可靠性结合在一起。PI将开发适用于宽带相干太赫兹辐射的波导技术。波导耦合的宽带太赫兹光谱仪将实现许多类型的测量，这些测量目前使用现有技术是不可行的。这些进展还将极大地简化光谱仪的使用，从而极大地扩大其对分析化学界的可及性。波导将允许许多目前不可行的测量，例如那些需要进入受限位置的测量，或者那些需要长相互作用长度的测量。太赫兹内窥镜检查就是一个很好的例子。

With support from the Chemistry Research Instrumentation and Facilities - Instrument Development (CRIF-ID) Program, Daniel M. Mittleman in the Departments of Electrical and Computer Engineering at Rice University will develop a terahertz spectrometer that combines the many useful capabilities of time-domain spectroscopy with the ease of use and reliability of a commercial FTIR system. The PI will develop waveguide techniques that are useful for broadband coherent terahertz radiation. The waveguide-coupled broadband terahertz spectrometer will enable many types of measurements that are not now feasible using existing techniques. These advances will also dramatically simplify the use of the spectrometer, and therefore vastly broaden its accessibility to the analytical chemistry community. Waveguides will permit many measurements that are not now feasible, such as those that require access to restricted locations or those that require long interaction lengths. A good example is terahertz endoscopy.
