This work is aimed at creating new types of portable sources and detectors of radiation. These will be handheld, about the size of a normal torch, and will run off batteries. They work in the terahertz (THz) range, this can be thought of either as very high frequency radio waves or as light which is invisible to the human eye. For a long time it has been quite difficult to generate and detect THz, but over recent years people have used large powerful lasers to create pulses of THz radiation. This has proved very useful in medical applications to build up pictures of body tissue, rather like an x-ray, which can show up abnormalities. Other interesting areas being studied include using THz in fossil imaging, analysing chemicals and gases, in security and in astronomy.The work in the project aims to make a new generation of THz 'torches' and 'cameras' which can be carried in the pocket. Making the devices, small, low power and portable, will allow people to use THz radiation in applications like airport security to screen for explosive chemicals or drugs, to look for pollution in the local environment, and even to be used in pharmacies or GPs for helping with diagnosis. Moreover the radiation they use will be very 'pure' and that will help to make very sensitive detection.A feature of the work is to build upon the optoelectronic technologies developed for optical communications systems which provides a good foundation of advanced fabrication techniques leading to high reliability components capable of low power and efficient room temperature operation. UCL, Bath and Essex will work together with the Centre for Integrated Photonics (CIP), to design, fabricate and characterise novel components for THz operation. Leeds will focus on users and applications issues undertaking a detailed comparison between the performances of old and new systems.

这项工作旨在创造新型便携式辐射源和探测器。它们将是手持式的，大小与普通手电筒差不多，并且需要电池供电。它们工作在太赫兹 (THz) 范围内，这可以被视为非常高频的无线电波或人眼不可见的光。很长一段时间以来，产生和检测太赫兹都是相当困难的，但近年来，人们已经使用大型强大的激光器来产生太赫兹辐射脉冲。事实证明，这在医学应用中非常有用，可以构建身体组织的图像，就像可以显示异常情况的 X 射线一样。正在研究的其他有趣领域包括在化石成像、分析化学品和气体、安全和天文学中使用太赫兹。该项目的工作目标是制造可以放在口袋里的新一代太赫兹“火炬”和“相机”。制造小型、低功耗和便携式设备将使人们能够在机场安检等应用中使用太赫兹辐射来筛查爆炸性化学品或药物，寻找当地环境中的污染，甚至用于药房或全科医生帮助诊断。此外，它们使用的辐射将非常“纯净”，这将有助于进行非常灵敏的检测。这项工作的一个特点是建立在为光通信系统开发的光电技术的基础上，这为先进的制造技术提供了良好的基础，从而导致能够低功耗和高效室温运行的高可靠性组件。伦敦大学学院、巴斯和埃塞克斯将与集成光子学中心 (CIP) 合作，设计、制造和表征用于太赫兹操作的新型组件。利兹将重点关注用户和应用程序问题，对新旧系统的性能进行详细比较。
