Terahertz Technologies Market Trends

Defense and Security End-User Segment is Expected to Hold Significant Market Share


- As the focus on detecting concealed explosives intensifies, terahertz technology is garnering heightened interest for security and defense applications. A hallmark of terahertz technology is its capability to unveil objects obscured by barriers. Thanks to terahertz beams, security personnel can now identify threats like ceramic knives or plastic explosives-non-metallic substances often overlooked-at airports and other high-security venues. This detection prowess stems from T-rays' ability to penetrate clothing while being blocked by the body's upper skin due to its water content.
- Traditional methods like metal detection and X-ray bag scanning can be laborious, especially in bustling public transportation hubs. This underscores the demand for advanced technological solutions capable of conducting security checks from a distance. terahertz technology rises to the occasion, enabling the scanning of numerous individuals without necessitating halts for security checks.
- A groundbreaking device has emerged, generating outputs that surpass the strength of conventional terahertz waves and can be directed with greater precision. This advancement not only fuels innovation and product development across diverse sectors but also bolsters industries and communities harnessing terahertz wave technology. The military potential of terahertz sensors is vast, especially in intelligence, surveillance, and reconnaissance (ISR) roles, such as pinpointing isolated personnel behind enemy lines, target acquisition, and guiding precision munitions.
- Moreover, for the fiscal year 2023-24, India earmarked INR 5.94 trillion (USD 72.6 billion) for defense, marking a 13% uptick from the prior year. This budget aims to bolster India's defense capabilities, including the procurement of fighter jets and infrastructure development along its contentious border with China. These escalating defense expenditures across nations underscore a burgeoning demand for terahertz technology.
- The increasing defense expenditure by countries across the globe is also driving the demand for military aircraft. For instance, according to estimates by Flight Global, a major firm tracking global defense aircraft dynamics, the United States is anticipated to maintain its position as the country with the highest number of military aircraft (13,209) among NATO countries and globally.
- As demand for defense aircraft continues to rise, the adoption of terahertz technology in this segment is set to increase. For instance, terahertz systems can inspect high-performance coatings on military aircraft, ensuring coating thickness is verified with submicron accuracy. Additionally, terahertz measurements play a crucial role in facilitating in-service inspections and repairs of these external coatings. Furthermore, according to Luna Innovations, using a single sensor, terahertz measurement systems can verify the structure of multilayer materials. When equipped with a line scanner gauge, a terahertz system can generate B-scan images to detect defects, analyze subsurface structures, or deliver accurate offset and separation measurements.


North America Holds Largest Market Share


- The United States is a key market for terahertz technologies, primarily owing to the growing homeland security issues, investments in defense, and R&D. In addition, the stringent government regulations regarding the safety and production of aerospace technologies in the US and the growing automotive and aerospace industries are driving the market for Terahertz technologies in the regional market.
- According to the Aerospace Industries Association, the aerospace and defense (A&D) industry generated USD 955 billion in total business output in 2023. Output directly from the industry totaled USD 533 billion, and an additional nearly USD 422 billion in indirect activity was generated through the domestic aerospace and defense (A&D) supply chain. The aerospace and defense (A&D) industry generated USD 425 billion in economic value, representing 1.6 percent of the 2023 nominal GDP in the U.S. Such heightened growth from the aircraft industry is a significant driver for the growth of inspection systems based on terahertz technology.
