headquarters platinum building st john s innovation park cambridge united kingdom area served worldwide key people don arnone ceo sir michael pepper chief scientific director products terahertz imaging and spectroscopy equipment number of employees 24 2013 website teraview teraview limited or teraview is a company that designs terahertz imaging and spectroscopy instruments and equipment for measurement and evaluation of pharmaceutical tablets nanomaterials ceramics and composites integrated circuit chips and more . 1 teraview was co founded by michael pepper cso and dr don arnone ceo as a spin out of toshiba research europe in april 2001 . 2 the company was set up to exploit the intellectual property and expertise developed in sourcing and detecting terahertz radiation 1 thz 33.3 cm 1 using semiconductor technologies . leading industry proponents of the technology sit on its advisory board and teraview maintains close links with the cavendish laboratory 3 at the university of cambridge which was one of the research universities which had an interest in terahertz techniques . it is also where professor pepper 4 has held the position of professor of physics since 1987 .

semiconductor industry 3 see also 4 references 5 external links products edit teraview has developed a number of instruments that harness the properties of terahertz radiation . 5 terahertz light has some interesting application . many common materials and living tissues are semi transparent and have terahertz fingerprints 6 7 permitting them to be imaged identified and analyzed . moreover the non ionizing properties of terahertz radiation and the relatively low power levels used 8 indicate that it is safe . 9 tps spectra 3000 spectrometer with modular sample compartment for transmission attenuated total reflection analysis cryostats variable temperature cells and reflection modules for imaging . 5 spectral range 0.06 thz to 3.6 thz 2 cm 1 120 cm 1 . eotpr 2000 electro optical terahertz pulsed reflectometer spectrometer for identification and isolation of faults on interconnects of advanced packages such as flip chip package on package pop and potentially through silicon vias . 5 cw spectra 400 continuous wave terahertz spectrometer with imaging capabilities that utilizes gaas based photomixers and optical fibres . 5 by applying different software analysis packages the same base technologies can be brought to bear to several applications . research and development areas edit main article terahertz radiation the company s primary focus of investigation includes the development of terahertz light into a usefulspectroscopic and imaging technique . the terahertz gap where until recently bright sources of light and sensitive means of detection were difficult to access encompasses frequencies invisible to the naked eye in the electromagnetic spectrum lying between microwave and infrared in the range from 0.3 to 3thz . teraview s existing instruments generate detect and manipulate thz light and have been tested in a number of application areas . pharmaceutical industry edit the applications of terahertz radiation in the pharmaceutical industry include nondestructive estimation of critical quality attributes in pharmaceutical products 10 11 such as crystalline structure 12 thickness and chemical composition analysis . 13 teraview has demonstrated that terahertz instruments can produce 3d coating thickness maps 14 for multiple coating layers 15 and structural features models 16 allowing better understanding and control of product scale up and manufacture . 17 medical imaging edit due in part to its ability to recognize spectral fingerprints terahertz pulsed imaging can be applied to provide contrast between different types of soft tissue . 18 also it is a sensitive means of detecting the degree of water content 19 and markers of cancer 20 and other diseases . 21 22 attempts have been made to apply terahertz to image cancers like breast 23 cancer as well as other diseases in medicine oral health care and related areas . the company announced it has been cleared by the medicines and healthcare products regulatory agency mhra to trial in vivo terahertz spectroscopy for bio medical research . 24 the trials will be held in guy s hospital in london and aim to determine if the technology can be applied real time for accurate removal of cancer tissue . 25 homeland security and defense edit terahertz technology has the potential 26 to safely noninvasively and quickly image through different types of clothing and other concealment and confusion materials . 27 it has been hypothesized that because thz light is absorbed by explosive materials 28 at certain frequencies it may be possible to find unique terahertz fingerprints 29 that can be distinguished from clothing or other materials . 30 this has never been proved in a practical sense . the company s technology has been used by the naval surface warfare command to test the presence of different types of plastic explosives through clothing including petn pentaerythritol tetranitrate . 31 material characterization edit main article terahertz metamaterials thz spectroscopy can be used as a non contact analytical method . 32 the absorption coefficient and refractive index 33 measured by terahertz pulsed spectroscopy can be used directly to obtain the high frequency dependent complex conductivities of materials 34 in the 0.1 3 thz 3 100 cm 1 region of the electromagnetic spectrum . 35 the technology has been applied to some areas of solid state physics research such as semiconductors 36 high temperature superconductors 37 terahertz metamaterials carrier density dynamics graphene 38 carbon nanotubes 34 magnetism and more . 39 nondestructive testing edit main article terahertz nondestructive evaluation terahertz light can be used as non contact technique for analysis in material integrity studies . it has proved to be effective in nondestructive inspection of layers in paints and coatings 40 detecting structural defects in ceramic and composite materials 41 and imaging the physical structure of paintings and manuscripts . 42 43 the use of thz waves for non destructive evaluation enables inspection of multi layered structures and can identify abnormalities from foreign material inclusions disbond and delamination mechanical impact damage heat damage and water or hydraulic fluid ingression . 44 the company s chief scientific director sir michael pepper explains that thz imaging can measure thickness across a substrate precisely and it can also obtain the density of the coating the radiation is reflected each time there is a change in material . the time of arrival is measured and then various algorithms complete the picture by developing 3d fine feature images and precise material identifications . 45 further research by the company and active collaboration with the university of cambridge is aiming to develop a terahertz sensor that can be used to measure the quality of paint coatings on cars . 46 semiconductor industry edit terahertz technology allows high resolution 3d imaging of semiconductor packages and integrated circuit devices . 36 thz time domain reflectometry tdr offers significant advantages in imaging resolution compared to existing fault isolation techniques and conventional millimetre wave systems . 47 working with intel on the applications of thz technology for the semiconductor industry teraview developed a new technique which combines electro optics and thz pulses in a non destructive electro optical terahertz pulsed reflectometry eotpr which operates at up to 2 thz with resolution of 10 m for improved fault isolation and failure analysis process flow studies . 48 the unique capabilities of terahartz tdr and its advantages over the conventional tdr have been recognized . with such revolutionary concept innovative design and superior performance eotpr will become an essential tool for microelectronic package fault isolation and failure analysis . yongming cai zhiyong wang rajen dias and deepak goyal intel corporation . 49 see also edit terahertz radiation terahertz time domain
