Abstract
The invention discloses a sensor system characterizing a coating such as a paint film by THz radiation. The sensor system for characterizing a coating 4, such as a paint film, of a coated body 2 in a non-contact manner by use of THz radiation is provided. The sensor system comprises a THz system 1, a processing unit 30 and a positioning system 40. The THz system 1 comprises a light source 50 for generating a source light radiation; a flexible first radiation guide cable 51 for transmitting the source light radiation; a THz emitter 10 comprising a THz radiation generator 12 and a THz optical system 14; and a THz detector 20. The positioning system 40 comprises a movable unit 42 carrying the THz emitter 10. The light source 50 is arranged outside of the movable unit 42. The processing unit 30 is operationally coupled to the THz detector 20.
