What Is THz?
Small Waves, Large Capabilities
Terahertz (THz) is used to reference energy in the range between traditional electronic frequencies (above microwaves) and traditional optical frequencies (the low end of the infrared range).
THz imaging is important because not only can it penetrate materials like x-rays, but the radiation is non-harmful.
Additionally, THz waves contain a wealth of information that allow immediate identification of materials and compounds. These include:
o looking through clothing for concealed weapons,
o identification of materials and explosives,
o quality control for chip-makers,
o and life-changing applications such as breast cancer detection.
The size of THz rays range from approximately 1 mm (300 GHz) to 30 microns (10 THz). The THz frequency range has been referred to as the “last frontier” of the electromagnetic spectrum due to the historical difficulty in producing it.
Due to the long-standing difficulty in generating stable THz sources (THz is faster than traditional electronics and too slow for optical materials), THz applications have been used in a few specially-equipped research labs and have seen limited commercial success.
Traycer is out to change the THz landscape.
The challenges of constructing a working measurement platform had to be met before the real work could begin. Yet, the promise of the additional experimental insight that THz data could provide seemed to justify such efforts.
