Terahertz-Measurement Methods

Time of flight measurement of ultrashort THz pulses in combination with broadband spectroscopy enable numerous applications in the field of non-destructive testing, safety engineering and tomography:

• Examination of layers in transmission/reflection: determination of thickness, homogeneity and delamination of layers and multiple-layer systems
• Examination of closed plastic containers: control of contents, level measurement
• Contactless counting of paper sheets
• Homogeneity examination of polystyrene components (for example templates for metal casting)
• 2-dimensional spectroscopy measurements of closed letters and packages to test for drugs, weapons and explosives
• THz Tomography: 3-dimensional reconstruction of components
