Plenty of new devices, the most famous being airport security scanners, have been developed to use terahertz waves to see through things. Fitting somewhere between microwaves and infrared on the electromagnetic spectrum, the terahertz wave is able to penetrate through porous material such as clothing and wood, allowing the airports security personnel to see if you’re hiding something in your underwear. Also medical and consumers uses are easily conceivable, as terahertzs vision creates a “X-ray vision”. Recent researches, however, showed that terahertz radiations can literally unzip the DNA structure, so that exposure to these rays may be very dangerous. A trendy technology with an uncertain future.
