介绍了利用非致冷测辐射热计型红外焦平面阵列和量子级联激光器实现太赫兹实时成像的技术。介绍了基于红外技术的太赫兹焦平面阵列和太赫兹成像器的发展，特别是辐射热计型焦平面阵列的太赫兹灵敏度和透镜、真空封装窗口材料的太赫兹透过率的提高。介绍了320 × 240 THz焦平面的特性，如噪声等效功率（NEP）与波长的关系和实时THz图像。其中一幅图像表明，太赫兹技术有望用于小分子与蛋白质反应的无标记检测。(C)2010年科学院。由Elsevier Masson SAS出版。All rights reserved.
Real-time Terahertz (THz) imaging technologies which make use of uncooled bolometer-type infrared focal plane arrays (FPAs) and quantum cascade lasers (QCLs) will be reviewed. A description of how THz focal plane array and THz imagers have been developed on the basis of infrared technologies, especially the improvement in both THz sensitivity of bolometer-type FPA and THz transmittance of materials for lens and vacuum package window will be given. Characteristics of 320 x 240 THz-FPA, such as relation of noise equivalent power (NEP) to wavelength and real-time THz imageries will be presented. One of the imageries indicates that THz technology is promising for label-free detection of reaction of small molecules with proteins. (C) 2010 Academie des sciences.
