The APAC terahertz technology market is expected to grow from US$ 51.6 million in 2019 to US$ 395.3 million by 2027; it is estimated to grow at a CAGR of 29.2% from 2020 to 2027.
The use of ionizing radiations (X-rays) is critical in quality control and nondestructive testing because of its detrimental effect on biological agents. In the food industry, food manufacturers and packagers can use terahertz food scanners instead of using X-ray machines to check abnormalities; for example, it can detect the misplacement or inadequate placement of candy bars in carton by a pick-and-place robotic arm. The THz imagers face no problem seeing through cardboard or PE packaging, and this allows packaging departments to wrap individual chocolate bars in any material, including metal-containing foil, impervious to the THz rays. Growing demand of terahertz technology in defense, homeland security, and medical industries is among the other factors that would add to the demand for the terahertz technology in APAC.

The terahertz detector led the terahertz technology market based on component in 2019. Terahertz radiation falls between the microwaves and far infrared portion of the electromagnetic spectrum. These radiations have the capability to penetrate through plastics, clothing, and wood, among other materials; their non-ionizing behavior makes them safer for individuals, compared to X-rays that can be harmful. Terahertz radiations are widely utilized in full body scan machines installed at airports and other public places for security purposes. These machines are also used in medical applications for initial cancer cell detection. Terahertz radiations fall in the frequency range from roughly 0.1 THz to 10 THz, corresponding to wavelengths from 3 mm down to 30 ?m. These frequencies are tough to identify with traditional means of electronics, which are capable to access only the lower end of terahertz region. As a result, several other methods for terahertz detection have been designed and developed; a few of these include the use of photonics. Terahertz radiation can be detected and measured through Micro-bolometers, GolayCells, pyroelectric detectors, Schottky diode detectors, and photo-acoustic detectors, which is ultimately drives the market for this technology. The ongoing COVID-19 pandemic is anticipated to cause huge disruptions in the growth of various industries in APAC. For instance, China is the global hub of manufacturing and largest raw material supplier for various industries and it is one of the worst affected COVID-19 countries.
