设计并制造了一种实用型安全检测系统。该系统应用了最新的准光技术及毫米波人体扫描技术。 实测结果表明，在工作频率为35 GHz (8.57 mm)的模式下，该系统的分辨率优于10.2 mm；可以检测微量粉末，比如0.5 g 金属与非金属混合物；可以在100 s内完成对600 mm×1800 mm大小区域的检测，基本达到了实用性要求。检测实验结果 表明，该系统可以应用于贵重金属探测等某些特殊应用场合。

A practical security system for human body inspection was designed and manufactured. In this system, the newest quasi-optical technology and the active millimeter wave (MMW) scanning technology were used. The experimental result showed that the system had a resolution better than 10.2 mm in an operation mode at a frequency of 35 GHz (8.57 mm). It could inspect trace powder such as 0.5 g metal or nonmetal fixture and could complete the inspection over an area of 600 mm×1800 mm within 100 s, which had met the requirement for practical use. The inspection experiment showed that the system could be used in some special applications such as noble metal detection.
