The properties of terahertz (THz) radiation make it possible to inspect a variety of non-conductive materials, such as paper, plastic, cloth, etc., without causing damage to the human body. THz wave characteristics have been used in numerous studies on application systems for non-destructive and manufacturing process monitoring as a result.
In this presentation, we introduce how to set up a contactless thickness monitoring system with long-term signal stabilization of CW THz signals to achieve signal stabilization within 1% for 12 hours insensitive to changes in ambient temperature.
