| Outline of Final Research Achievements |
The purpose of this research is to establish the evaluation method for plastic internal physical property using THz polarization. First, by using THz-TDS, we have confirmed that many plastics should show interesting characteristics in 2-4 THz regions derived from their crystal orientations and internal forces. Then we have developed THz source with CW sources to proceed THz polarization experiments. In addition, we have experimentally confirmed that moisture contents of pulp injection molded products could be accurately estimated with THz measurement.
