The
world of imaging technology is evolving, and scientists and researchers in the
manufacturing industry are using terahertz on different applications. The
increasing number of areas that demand the use of this technology is an
indication of the growing level of trust new advancements.
Brief
overviews of the application that require the use of a terahertz detector are:
Security: used in
immigration offices and entry points for screening
Pharmaceuticals
and Food Industries: food and drug inspections as well as quality controls
Ceramic industry: inspection and
processing
Automotive: conduct various
testing during the assembly plant
Science: used in beam
profiling systems
Medicine: used in medical
diagnosis
Security
The global
terror menace has driven many countries to implement tight border security
controls. The use of terahertz detector in
body scanners and x-ray machines enables the waves to pass through your body
and some enclosures to give the guards assurance that no contraband passes
through them.
Pharmaceuticals and Food Industries
The
pharmaceuticals and food industry use materials that are transparent to waves
produced by the terahertz devices. The use of non-destructive testing (NDT) on
drugs and food products in the process line assures consumers of product
quality.
In the food
and agricultural sector, the waves from the terahertz detector can detect
foreign bodies inside the food package or containers. You can also use the same
technology to check the quality of agricultural products such as seeds and
nuts.
Ceramic Industry
In the
ceramics industry, you will notice that they use a high-speed linear scanner,
which checks for quality control marks. In this industry, the high terahertz
affinity to impurities and additions will detect any inclusions on non-ceramic
materials such as plastic and wood. The variation of density and humidity after
the kiln process can also be detected.
Automotive
The
breakthrough in semiconductor technology has expanded the limits within which
terahertz can operate. Terahertz devices are used in the automotive industry to
detect the nature of steel reinforcement and any other foreign element inside
the rubber parts of the car. The detector can also show the level of corrosion
in metals.
Science
New
research in material science has expanded the frequency within which terahertz
waves can use. Other applications enabled by consistency in scientific research
include wireless communication, security applications, medical diagnostics,
food packaging, and many more.
The most
recent applications of terahertz imaging cameras have been in the field of
astronomy and lab research. Another use of the terahertz camera is the beam
profiling and measurements using spectroscopy systems.
Medicine
The
chemical bonds and reactions taking place in living organisms are strong enough
to withstand the waves from devices carrying terahertz waves. The high
absorption rate of terahertz rays in water makes them highly appropriate for
various medical applications that require noninvasive techniques such as the
detection of early cancer or in dental surgery.
Wood
The use of
infrared moisture sensors and visible light optical scanners give better
imaging of timber during processing. You can use terahertz waves to see the
hidden defects in wood, which cannot be seen by the naked eye.
