摘　　要：自制的太赫兹量子级联激光器性能良好且易于集成和实际应用。利用该激光器出射的太赫兹波对非金属物质的穿透性,在该激光器中配以辅助光路与阵列接收模块,设计出具有一定空间尺度和分辨率的透射式成像系统,对该成像系统中的光束整形关键参数选择因素进行了分析。将此成像系统与基于光电导天线对收发的全光纤太赫兹时域光谱系统相结合,实现了联动式太赫兹分析仪的设计。此联动式太赫兹分析仪可对非金属包装中的隐匿物品进行太赫兹波段成像与指纹谱的联动获取,整机操作软件能在后台控制与监控内部各设备,实现了对危险品的快速、直观、准确的定位以及对物品种类的无损分析。A terahertz quantum cascade laser, which is made in-house, has excellent device performance and is easy for integration and application. Terahertz wave emitted from the laser device can penetrate non-metal materials with little loss. A transmission imaging system with certain spatial dimension and resolution is built with the terahertz quantum cascade laser together with peripheral supporting optics and an array receiving module. Key parameters in the beam shaping are studied. A terahertz joint analyzer is developed by using the imaging system together with an all fiber terahertz time domain spectrum system based on photoconductive antenna. The terahertz joint analyzer can detect both terahertz imaging and fingerprints of objects hidden in non-metal packaging. The operation software of the whole instrument can control and monitor all the devices inside. The terahertz joint analyzer system offers a method of fast, intuitive and accurate location and non-destructive analysis for the detecting objects.
