TeraSense devices bridge the gap of 0.1 – 1.0 THz since exploiting this particular frequency band has been arousing increasingly more interest as it opens far-reaching possibilities for creating the state-of-the-art visualization solutions to meet the growing demand for sophisticated yet cost-effective instrumentation. Owing to its harmless and versatile nature, there is whole host of viable practical applications of THz imaging technology to be realized, from nondestructive industrial product quality control in manufacturing and agriculture to noninvasive medical diagnostics and security screening. The use of THz devices will undoubtedly proliferate in the nearest future as this innovative technology is imminently coming to take its due place in many areas of our lives.

TeraSense custom-builds complete fully-operational terahertz imaging systems equipped with software and all necessary hardware components, including a camera with 2D sensor array, one or more signal generators with output horn antennas and complementary optics. Using discrete modules allows to adapt the system to meet desired specifications of operating frequency, power level, physical shape and dimensions of the detector area and overall geometrical configuration. What is more, due to their compact size and functional flexibility, TeraSense imaging systems can be easily integrated into more elaborate industrial solutions.

Terahertz imaging

TeraSense fabricates low-cost 2D semiconductor sensor arrays scalable to match required shape and dimensions, from a square to a linear matrix, with available pixel sizes of 0.5×0.5, 1.5×1.5 and 3.0×3.0 millimeters. These arrays are utilized to construct cost-effective, highly sensitive and exceptionally compact terahertz cameras capable of ultra-fast registration rate of up to 5000 fps. As this novel technology presently outranks any competition, it has great potential to become an expedient element in a broad scope of hi-tech applications, such as:-

THz non-destructive testing

Security screening

Medical imaging (THz tomography)

Terahertz communication

Terahertz signal generation

For the terahertz signal generation purposes TeraSense makes use of proprietary IMPATT and Schottky-diode technologies. Designed to operate in sub-terahertz frequency range of 0.1 – 0.3 THz, these cutting-edge devices are currently some of the most powerful solid-state THz sources on the market that have capacity to generate a continuous Wave (cw) signal with output power level of up to 0.5 W. All TeraSense generators boast exceptionally long life of fully stable and reliable operation. Moreover, it is their remarkably compact size and low cost that put these devices in the vanguard of the competition. All these advantages imply numerous possibilities in terms of both small and large-scale applications as they enable straightforward integration of TeraSense sources as stand-alone units into complex industrial systems.
