许多应用领域，如无损检测（NDT）、安全、食品和农产品工业的质量控制，都需要集成在紧凑和手持相机中的灵敏和大画幅太赫兹焦平面阵列（fpa），以提供实时太赫兹（THz）成像。CEA-Leti正在研究的两种非冷却太赫兹阵列技术，即测热计和互补金属氧化物半导体（CMOS）场效应晶体管（FET），能够满足这些要求。本文回顾了以下技术途径，重点介绍了最新的建模和性能分析。这些阵列应用于无损检测和安全的能力，然后通过实验测试证明。特别是，通过在完整的人体扫描仪原型中实现对不透明场景的大视场的快速扫描，说明了太赫兹测热仪相机的高技术成熟度。
Sensitive and large-format terahertz focal plane arrays (FPAs) integrated in compact and hand-held cameras that deliver real-time terahertz (THz) imaging are required for many application fields, such as non-destructive testing (NDT), security, quality control of food, and agricultural products industry. Two technologies of uncooled THz arrays that are being studied at CEA-Leti, i.e., bolometer and complementary metal oxide semiconductor (CMOS) field effect transistors (FET), are able to meet these requirements. This paper reminds the followed technological approaches and focuses on the latest modeling and performance analysis. The capabilities of application of these arrays to NDT and security are then demonstrated with experimental tests. In particular, high technological maturity of the THz bolometer camera is illustrated with fast scanning of large field of view of opaque scenes achieved in a complete body scanner prototype.
