SIG 6: Non-Destructive Testing, Security and Process Monitoring

The Special Interest Group (SIG) for Non-Destructive Testing (NDT), Security, and Process Monitoring aims to accelerate both the development of Terahertz (THz)-based NDT techniques and the adoption of THz technologies across industrial sectors. Our goal is to create a collaborative, challenge-led environment that connects academic researchers, THz equipment developers, national laboratories and industrial end-users of different scales and sectors to drive real-world impact.

We will work closely with British Institute for Non-Destructive Testing (BINDT) and the Research Centre for Non-Destructive Evaluation (RCNDE). In particular, each meeting will include talks from BINDT members, providing valuable insight on industrial needs, operational constraints, and emerging challenges. Academic researchers will also be encouraged to present latest THz developments, case studies, and demonstrations to stimulate technological adoptions. We will also facilitate discussions with members to ensure that the SIG captures a wide spectrum of perspectives and addresses both scientific and practical deployment challenges. These interactions will help identify shared research priorities, highlight opportunities for joint projects, and promote the transition of THz technologies from laboratory development to robust, validated industrial solutions.

The SIG will cover the full spectrum of THz-enabled industrial NDT and process monitoring, including but not limited to:

Material characterisation

  • Defect detection across a wide range of materials
  • Measurement properties and variations
  • Multilayer structures
  • 2D and 3D imaging

THz technologies

  • Time-domain, frequency-modulated FMCW, and other broadband techniques
  • VNA and electronic techniques
  • Narrow-band systems
  • Passive detection methods

Validation and standards

  • Procedures and criteria for validation
  • Standardisation efforts
  • Verification and calibration methodologies

The SIG will encourage inclusive participation from early-career researchers, SMEs, underrepresented groups, and stakeholders new to THz technologies. By fostering cross-disciplinary engagement and promoting equitable access to expertise and resources, the group will stimulate innovation, enable knowledge exchange, and support the wider adoption of THz technologies in NDT.
