Abstract

THz spectroscopy has recently been used to examine human disease because of its a higher sensitivity and signal-to-noise ratio. In this work, the interaction mode between THZ radiation and biological tissue in the THz frequency range is given. Clinical Intralipid-10% is diluted into different concentrations to use as tissue phantoms. And they are firstly tested based on the terahertz time domain spectroscopy in the condition of room temperature. Optical parameters of phantom solution including absorption coefficient and refractive index are gotten, and the frequency properties of these optical parameters are analyzed. The function relations can be firstly found. The conclusions is meaningful to make the further research of interaction between THZ radiation and human tissue, related cancers.
