Abstract

Terahertz radiation has emerged as a prominent solution for imaging and detection beyond visible and infrared. Active terahertz imaging is a widely used technology in this context especially for security applications and screening. Such systems are built around an illuminating source, a detecting module and a beam shaping system to match the detectors geometry. The overall system performance is largely dependent on an optimized choice of these modules. In this work, an active sub-terahertz scanning system working at 100 GHz frequency is proposed to detect concealed objects in parcels and mail. The system is optimized based on an adapted design of the beam shaper and a preprocessing correction of the images to ensure uniformity of response and cleanness. The proposed system demonstrated through experimentation improved resolution with a uniform response along its detection area.

用于包裹检查的改进型主动式亚太赫兹成像系统

太赫兹辐射已成为超越可见光和红外线的成像和检测的重要解决方案。有源太赫兹成像技术在这方面得到了广泛应用，尤其是在安全应用和安检方面。这类系统由照明光源、探测模块和光束整形系统组成，以匹配探测器的几何形状。整个系统的性能在很大程度上取决于对这些模块的优化选择。在这项工作中，提出了一种工作频率为 100 GHz 的有源亚太赫兹扫描系统，用于探测包裹和邮件中的隐藏物体。该系统的优化基于对光束整形器的调整设计和对图像的预处理校正，以确保响应的一致性和清洁度。通过实验，拟议的系统提高了分辨率，其探测区域的响应均匀一致。

期刊介绍： Rapid progress in optics and photonics has broadened its application enormously into many branches, including information and communication technology, security, sensing, bio- and medical sciences, healthcare and chemistry. Recent achievements in other sciences have allowed continual discovery of new natural mysteries and formulation of challenging goals for optics that require further development of modern concepts and running fundamental research. The Journal of the European Optical Society – Rapid Publications (JEOS:RP) aims to tackle all of the aforementioned points in the form of prompt, scientific, high-quality communications that report on the latest findings. It presents emerging technologies and outlining strategic goals in optics and photonics. The journal covers both fundamental and applied topics, including but not limited to: Classical and quantum optics Light/matter interaction Optical communication Micro- and nanooptics Nonlinear optical phenomena Optical materials Optical metrology Optical spectroscopy Colour research Nano and metamaterials Modern photonics technology Optical engineering, design and instrumentation Optical applications in bio-physics and medicine Interdisciplinary fields using photonics, such as in energy, climate change and cultural heritage The journal aims to provide readers with recent and important achievements in optics/photonics and, as its name suggests, it strives for the shortest possible publication time.
