Terahertz Imaging

TeraSense has developed and patented a ground-breaking technology for making new-generation semiconductor imaging systems for Terahertz (THz) and sub-THz frequency ranges.


Terahertz Imaging Cameras

Terahertz area imagers are available with 256 , 1024 and 4096 pixels. The terahertz cameras are active detecting devices, and require an external THz source. TeraSense offer sub-terahertz wave sources based on IMPATT technology. All our TERA-series THz imaging cameras employ the same type of detectors with identical capabilities and spatial resolution. The difference between our models lies in the number of pixels in their sensor arrays and their effective imaging area.


Linear Imaging Cameras

The High-Speed Terahertz Imaging Scanner is our flagship product. It features both, an unprecedented imaging speed of 5000 frames per second and ease of integration into any industrial process. The Terahertz Imaging Scanner fits most conveyors with a belt speed up to 15 m/s. Its ultrafast linear sensor array is built to satisfy the needs in Non-Destructive Testing (NDT) and Quality Control (QC) for many industrial applications. Two models are available, 100GHz and 300GHz


Other Products

TerasSense have developed a range of other products. 
These include :-
- THz security screening system for the detection of hidden objects under clothes (weapons, drugs, explosives).
- The TeraSense series of terahertz sources (IMPATT diodes)
Ultrafast Terahertz detectors
- Terahertz Optics
- Microwave and terahertz horn antennas

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.
