G-Tronix Ltd is scientific research company focussed on the development of innovative imaging techniques and products for a variety of applications. Near-infrared, air-coupled ultrasound and capacitive imaging and are the primary technologies that have been widely exploited by the company. Since its inception G-Tronix has enjoyed great success in developing new imaging techniques for food inspection, non-destructive evaluation (NDE), security and aerospace applications. The innovative products developed at G-Tronix are currently replacing existing traditional inspection/measurement equipment with fully automated state-of-the-art sensory systems which will deliver greater value to the industry. The areas of interest here concern primarily near-infrared techniques, which the company has been developing for materials inspection and NDE applications. In addition, the remote measurement of dielectric properties, another technology that the company specialises in, is of interest as an additional non-contact inspection technique.
