Automotive industry applications

Research into new materials and semiconductor technology has expanded the existing boundaries to the terahertz extremes which opened doors for commercializing the THz technologies in numerous markets and various applications.

Terasense’s technology shows promise for such applications as detection of disrupted steel (and nylon) reinforcement and foreign inclusions inside rubber parts and detection of corrosion in coated metal parts.

Case 1. Detection of disrupted steel reinforcement
in rubber belt

As a safe and cost-saving alternative to x-ray systems used in quality control applications, TeraSense offers its high-speed linear THz scanning system for conveyor applications.

Case 2. Detection of corrosion in metal parts

Most metal automotive parts are exposed to corrosion, but it is often difficult to determine it due to the fact that those parts are coated with paint as, for example, body parts. In other cases, steel reinforcement of rubber belts or tires is subjected to corrosion.

Much poorer reflection of the THz signal is observed from the corroded metal part than from plain metal without corrosion.
