Summary: 
A Korean R&D institute specialised in cost-effective, high-speed Terahertz imaging technology using a single polygon mirror wishes to expand its overseas market through license agreement, technical cooperation and commercial agreement with technical assistance. The technology enables user to determine whether cancer is included in lesion tissue extracted in real time within a few seconds during the operation and any organisations in need of such a technology can be potential partners.
Description: 
Terahertz (THz) waves, as the electromagnetic waves in the frequency band of 100GHz to 10THz, are useful for non-destructively inspecting the inside of an object. Contrastively, the X-rays are harmless to living bodies for their relatively low energy (~4meV), thereby being used for industrial applications such as industrial non-destructive testing (NDT). In particular, THz waves are able to detect lesions in biological tissues due to their high sensitivity to water and biochemical substances, leading to the development of a device that provides label-free method for the tumour discrimination and delineation of tumour margins in brain tissue. The simplest way to get a two-dimensional image is to use two-dimensional light sources and detectors, but in the THz range, components of high-powered sources and two-dimensional array detectors are highly expensive to be run at industrial site. For this reason, it can be a cost-effective way to obtain a two-dimensional image that uses a single emitter and detector with a scanning mirror. It is also one of the methods that can have a high-resolution image with a high signal-to-noise ratio with a low-powered source. Currently, one of the most popular mirror scanning structures would be the Galvano-mirror that repeatedly moves in a certain range of angles. However, in order to perform high-speed repetitive motion of the reflective mirror, a motor with a large torque can quickly switch the direction against the large inertia. This can limit to the speed of the image acquisition. Moreover, for the higher resolutions, the larger reflective mirror would be required for the bigger beam diameter, which requires to greater inertia and larger motors. As a result, it leads to a problem that volume of entire system gets enlarged. In order to resolve the problem and implement the THz imaging technology, a Korean R&D institute has found a relatively low-cost solution. The costs of used parts, the size and the weight of the system are greatly reduced in their high-speed two-dimensional THz imaging technology. This technology has a structure, able to do high-speed scanning of an object in two-dimensions by rotating and tilting a single polygon structure with two (or one) motors. It is possible to manufacture the smallest, the simplest, relatively low-cost system (or scanning device) compared to the conventional structures. Additionally, by using a polygon instead of reflecting mirrors, the distances from a centre of rotation to all the reflection surfaces are minimised. This can increase the diameter of an incident beam, which is crucial for realising a high-resolution image, and also can minimise the image distortion due to the tilting of the reflection mirror. Plus, a clock signal extraction reflector is mounted on each reflector surface, aiming at monitoring the RPM (revolutions per minute) and processing image correction without using a high-cost motors in needs of bulky and expensive sensing and controlling parts to maintain a constant RPM of the high-speed rotating motor. Thus, low-cost, small motor can be installed, allowing the system to be downsized and used in the field where non-destructive detection is performed. Thus, it is expected that the THz scanner can be used as a diagnostic tool for the brain tumour and will determine in real time if cancer is included in lesion tissue that is extracted during the operation within a few seconds to minimise surgical delay time. Moreover, it can be used as a tool to conduct industrial non-destructive testing in various fields. The Korean R&D institute who developed cost-effective, high-speed Terahertz imaging technology using a single polygon mirror is now looking for global partners under license agreement, technical cooperation and commercial agreement with technical assistance. Companies or research institutes, interested in brain tumour diagnosis or Terahertz high speed medical imaging system can be potential partners.
