Terahertz Linear Array Fast Scanning Imaging
摘要
采用0.3 THz辐射源和线阵探测器,搭建了太赫兹线阵扫描成像系统。该成像系统完成100 mm×100 mm区域的测量仅需1 min,成像分辨率可达1.5 mm,可以准确识别聚乙烯样品和水管中预埋的缺陷,高精度定位隐藏在信封内的剪刀和小刀。研究结果表明,该成像技术可以快速检测隐蔽物,在无损探伤和安全检查领域具有一定的实用价值。
Abstract
A THz linear array scanning imaging system was built using a 0.3 THz radiation source and a linear array detector. The imaging system only needs 1 min to achieve an imaging measurement over a 100 mm×100 mm region at an imaging resolution of 1.5 mm. Using this imaging system, the defects embedded in polyethylene samples and water pipes as well as the scissors and knives concealed in envelopes are quickly and accurately identified. The research results demonstrate that the proposed imaging system can rapidly inspect various objects and is suitable for non-destructive testing and security inspection.
