Terahertz Technology and its Applications Speaker: For more than last forty years, terahertz components and instruments have primarily been developed for space science applications in radio astronomy and planetary sciences.
Science Beam profiling systems Security We all know that homeland terror knows no bounds and is currently on the rise. Security-related applications can be subdivided into two major subcategories outlined below.
Security screening of letters, envelopes and small packages Detecting powder, liquids, explosives and other threats in small packages and mail has recently become highly important. After discovering letters containing anthrax, such new threats as CBRE chemical, biological and radiological elements are perceived as real and requiring new and effective detection approaches to counter them.
Designed for inspecting flat objects envelopes, letters, small packagesour Terahertz imaging scanner offers a brand-new approach for security screening in terms of safety, accessibility and detection.

These properties make THz-based people screening solutions extremely valuable for applications where human health and safety are of utmost importance.
The TeraSense security body scanner operates in reflection mode and is intended for stand-off detection of weapons, including cold steel and firearms, bombs and grenades, explosive belts and various contraband items hidden under clothes. Read more about terahertz security screening of people Pharma There are a number of materials used in Pharmaceutical and Cosmetics industries which are fairly transparent in terahertz waves.

This is where terahertz imaging technology, developed and commercialized by TeraSense, is extremely useful; for instance, checking if a robotic arm has put all candy bars into the carton, or checking for foreign bodies and insects inside of packaged food containers.
Seeing through cardboard or PE packaging poses no problem to our THz imager. Checking the quality of various agricultural products like nuts and seeds also opens up huge perspectives for THz technology in this field too.
Ceramics The High-Speed Linear Terahertz Scanning system developed and manufactured by TeraSense for conveyor applications is a perfect solution for non-destructive testing and quality control of different materials in an industrial environment.
One of the key benefits of the TeraSense THz imaging technology is its high sensitivity to different features and inclusions in the volume of non-metallic materials ceramics, plastics, wood.

Yet despite the unique properties of the terahertz THz gap of the electromagnetic spectrum, THz imaging devices still do not top the list of wood-processing industrialists. However, there is no doubt that the high-speed THz imaging scanner solution from TeraSense is going to break the mold!
Detection of hidden defects in wood which are difficult to detect using other technologies, e. Such defects may include, but are not limited to, knots, hollows, and foreign bodies like nails, screw and wormholes, and rotten as well as wet areas.

THz radiation is not highly scattered in tissues unlike optical emission. Besides this, due to strong absorption of T-rays by water, terahertz imaging can be a useful tool to investigate soft tissues. These unique properties of T-rays make them eligible for use in various medical applications, some of which hold enormous promise, like a non-invasive technique for early detection of cancer, ex-vivo spectroscopy, dental care etc.
Read more about terahertz-based imaging in medical diagnostics Science Development of semiconductor technology and the research of new materials has expanded the utilized frequency limits to THz regions and opened doors for new applications in a number of industries such as wireless communication, homeland and personal security, medical diagnostics, FMCG packaging, food and wood processing, ceramic tiles production, and many more.
More recently terahertz technology has been used in only a few scientific applications in radio astronomy and lab research, and these terahertz systems were expensive and bulky solutions. Indeed, every research project has its specific requirements.Although terahertz technology has been much in the news lately, the phenomenon isn’t really new.
It just went by different names in the past—near millimeter, submillimeter, extreme far infrared. More recently terahertz technology has been used in only a few scientific applications in radio astronomy and lab research, and these terahertz systems were expensive and bulky solutions.

The talk will detail the science and other applications that specifically require technology at terahertz frequencies. The challenges of the future generation instruments and detectors at these frequencies in addressing the needs for critical scientific and commercial applications will also be discussed.
New advances in different technologies have made the previously unused terahertz frequency band accessible for imaging systems.
The ‘terahertz gap’ has a frequency ranges from ∼ THz to.
