Invited Talk: T-Ray – A powerful tool to see through things (Hsinchu MacKay Memorial Hospital, Taiwan)
Time: 9/17 (Mon) 0530pm-0730pm
Abstract：Terahertz technology has attracted extensive attention because of its unique applications in environmental monitoring, space explorations, chemical identification, security screening, medical imaging, and biological sensing. In the meantime, the practical feasibility of many terahertz systems is still limited by the relatively low power, low efficiency, and bulky nature of existing terahertz sources. In this talk, I will present some of our recent results on achieving high-performance terahertz sources to mitigate performance limitations of existing terahertz systems. With this generated terahertz power level, a terahertz tomography system can be achieved to offer a promising solution for early-stage cancer diagnosis since it can provide sub-millimeter image resolution with image depths ranging from 0.3-1 cm, depending on the tissue water content. Moreover, a terahertz tomography system allows detecting cancer biomarkers through a non-ionizing, nondestructive imaging platform. Additionally, the size of terahertz tomography systems can be further reduced by incorporating fiber systems and compact lasers, resulting in a breakthrough platform for in vivo biomedical imaging.
