Frequency multiplexing of terahertz sensors

我们建议开发一个多路复用系统读出的低温太赫兹传感器阵列。将使用设计系统的通用方法，以便将多路复用技术转移到不同类型的传感器：单电子晶体管，点接触，测辐射热计。多路复用系统的主要应用将是被动太赫兹成像仪，该成像仪目前正在伦敦皇家霍洛威大学（RHUL）和国家物理实验室（NPL）开发。多路复用系统将使用单条线路进行操作，并且它将以高速寻址传感器阵列，每个传感器低至10 ns。这将允许生成真实的时间图像或执行光谱快速分析。这种速度和性能的太赫兹成像仪将在天文学、安全、快速气体分析和健康成像等许多应用中取得突破。RHUL、NPL和指定研究人员T Lindstrom博士的补充专业知识将用于该项目的成功。RHUL为该项目带来了纳米制造设施和灵敏太赫兹探测器技术。NPL增加了用于高频操作的技术和设备，以及用于计量和工业需求的科学发展应用的专业知识。T Lindstrom博士是该项目的研究人员，他是低温下高频测量的专家。多路复用系统的开发是这些专业知识的有效协同。

We propose to develop a multiplexing system for read out of the array of low temperature terahertz sensors. The universal approach in designing the system will be used, so that the multiplexing technology will be transferable to the sensors of different types: single electron transistors, point contacts, bolometers. The prime application of the multiplexing system will be in a passive terahertz imager, which is currently under development at Royal Holloway University of London (RHUL) and National Physical Laboratory (NPL). The multiplexing system will use a single line for operation and it will address an array of sensors with a high speed, down to 10 ns per sensor. This will allow to generate a real time image or to perform a spectroscopic express analysis. The terahertz imager of this speed and performance will be a breakthrough in many applications including astronomy, security, express gas analysis and health imaging. Complementary expertise of RHUL, NPL and the named researcher, Dr T Lindstrom, will be used to success of the project. RHUL brings to the project the nanofabrication facilities and technology of sensitive terahertz detectors. NPL adds technology and equipment for the high frequency operation, and expertise in application of scientific developments for metrology and industrial needs. Dr T Lindstrom, the name researcher in the project, is an expert in high-frequency measurements at low temperatures. Development of the multiplexing system is an efficient synergy of these expertise.
