The existing full-body scanners used at most of the US airports bounce millimetre waves off passengers to spot objects hidden under their clothes. However, there are a few terahertz body scanning market players offering innovative body scanners that are safe and widely adopted.
Terahertz body scanners have a few advantages such as no ionizing radiation, extremely high image acquisition rates of up to 5,000 frames per second, easy integration into industrial processes, and low cost. Additionally, a new sub-terahertz security body scanner has been developed to respond to the urgent demand for efficient, safe, and speedy imaging in remote security screening applications. The integration of innovative THz sensing technique and advanced signal-generating technology based on IMPATT diode resulted in a cost-effective cutting-edge system capable of real-time visualization of the threats hidden under people’s clothes.
According to a report by The Insight Partners, Europe is expected to be a crucial region for the growth of the terahertz body scanning market in the future, owing to the presence of well-developed nations such as Germany, the UK, and France that drive the adoption of advanced body scanning-based security solutions. Additionally, the presence of a large number of terahertz body scanning manufacturers in this region further contributes to the growth of the terahertz body scanning market.
In terms of revenue, the global terahertz body scanning market was valued at US$ 48.54million in 2019 and is projected to reach US$ 316.09 million by 2027; it is expected to grow at a CAGR of 27.0% during the forecast period.
Other than the COVID-19 pandemic, the technology has been in demand due to the growing safety concerns from incidences of terrorism. Increasing terrorist activities and rising security threats to major economies have forced the government and other governing bodies to undertake air traffic controls such as the Federal Aviation Administration(FAA) to increase security scanning systems across all entry and exit points of the country.
The deployment of full-body scanners at airports has facilitated the reduction of fraudulent activities such as diamond smuggling, narcotics, weapons, and other expensive materials. Increased security screening systems that include a full-body scanner as one of the major components have successfully deteriorated the impact of terrorist activities on board.
Stand-alone terahertz scanners are the more traditional approach to security deployments. The installed systems include cameras and alarms. All standalone systems are managed and operated individually. Actions originated within each individual system have no impact on any other system. Thereby, single system failures do not impact the functioning of any other system. Each system can be upgraded individually, devoid of affecting other systems.
While the airport and custom checkpoints hold the largest share of the global terahertz body scanning market in 2019, these scanners could intensify the speed and dependability of security screening. However, this technology has not been widely adopted yet. For instance, only a few airports in the US have millimetre-wave scanners.
At present, the limited installations of these scanners make it hard to validate the investment required. Additionally, these scanners need people to stand still for a few seconds, a compulsion unsuitable with the ever-increasing volume of passengers.
