Abstract: A method of characterizing a coated body by at least one coating parameter based on fitting to a physical model is provided. The coated body includes a substrate coated by a polymeric coating such as a paint film, the polymeric coating having at least one layer. The method is carried out by a sensor system in a non-contact manner, the sensor system including an emitter system for emitting THz radiation, a detector system for detecting THz radiation, and a processing unit operationally coupled to the emitter system and the detector system. The method includes: emitting, by the emitter system, a THz radiation signal towards the coated body such that the THz radiation interacts with the polymeric coating; and detecting, by the detector system, a response signal being the detected THz radiation signal having interacted with the polymeric coating.
