燃料箱泡沫板的连续太赫兹波无损检测
Nondestructive Testing of Fuel Tank Foam with Continuous Wave Terahertz
摘 要
简要介绍了连续太赫兹波成像系统。该系统采用耿氏二极管作发射器，无偏置肖特基二极管作探测器，具有小型、简单和便携的特点。利用此系统探测了燃料箱绝缘泡沫板中的人工预埋缺陷。结果表明，使用太赫兹波成像方式在质量检测和材料无损检测领域具有广泛的应用前景。

Abstract
A terahertz continuous wave imaging system was reported. The system which utilizing a Gunn diode emitter and unbiased Schottky diode detector was compact, simple and portable. Some artificial defects in fuel tank insulation foam panel were detected. Testing results showed that the new technology could be widely used in quality monitoring and material inspection.
