| Outline of Final Research Achievements |
A quasi-elastic laser scattering (QELS) method utilizing capillary wave resonance has been investigated for measuring surface or interfacial tension of microscale liquid interface. In the resonant power spectrum of QELS method, characteristic peaks which are independent of the optical setup were observed and could be utilized for determining the tension. In this study, we have improved the QELS theory for power spectrum prediction, investigated microfluidic devices and optical apparatuses, and discussed 1-micrometer-sized small liquid interfaces.
