Terahertz Spectroscopy for Medical Instrumentation Development

Recent development of sources and detectors in the THz regime (300 GHz to 3 THz) has enabled the precise measurement of material properties, including complex refractive indexes and loss tangents. Using our developed THz spectrometer, new data, in particular, of biological tissues has been used to develop potential THz medical imaging applications. In this paper, an overview of a 0.1-3 THz, with sub-GHz resolution spectroscopy system is presented that has been designed in particular to measure biological samples and provide data that will used to determine initial viability of THz medical imaging applications.
