摘要
It is demanded a non-contact, non-destructive and reliable system and method of porosity measurement because conventional techniques are contact and cubersome. We have developed a method by using THz inspection system, which allows measuring the porosity rapidly and non-invasively, by introducing an external perturbation. The embodiments of the external perturbation can be mechanical or pulsed laser. (C) 2017 Elsevier Ltd. All rights reserved.
