摘要 介绍和讨论了Terahertz波相干层析成像技术(T-CT)。与X-射线计算机层析成像技术(X-CT)相比,Terahertz-CT可获得更丰富的信息来处理图像。理论上,该技术可获得被测物在Terahertz波段的复折射率的三维分布。这意味着有可能利用Terahertz-CT进行暗箱识别探测,该技术在安全检查和无损探测等方面有着广阔的前景。 T-ray coherent tomography technology (T-CT)is introduced. Compared with the X-ray computer tomography (X-CT), more information could be extracted to process the image. Theoretically, Terahertz-CT could be used to map the complex refractive index distribution in target 3 D space. Therefore, it is possible to employ the principle of Terahertz-CT to classify the target inside a black box, which implies potential applications in security inspection and nondestructive examination.
