Research Abstract |
The purpose of this research is to develop ultra-wideband THz spectroscopy system which can generate and detect from 1 to 20 THz waves. Then, to observe difference of absorptions caused by stretching and libration vibration modes between water molecules by using the system. We developed ATR spectroscopy system by using DAST and BNA crystals and then tried to spectroscopy measurement for water samples. Because of large absorption due to water and silicon prisme, no clear transmittance signals can be obtained yet. Modification of SN ratio of the system is under development.
