Mail Inspection Based on Terahertz Time-Domain Spectroscopy
Applied Sciences, 2021 One of the most prominent applications of terahertz time-domain spectroscopy is the spectral investigation of materials covered by visibly opaque objects. Therefore, terahertz waves are well suited to inspect the content of mail. We report on our work on
