| Research Abstract |
This paper reports for two detection systems of nanoparticles. One is a detection method for nano particles as phase image expanded lager than diffraction limit in diameter by using photothermal effect. To detect minimal phase difference, a near-common path interferometer using a beam splitter cube is presented. The other is a trapping system for nano-particles by periodically localized light and of a detecting system for the trapped state by an ellipsometoric method. There are possibilities for observing and imaging of nanoparticles.
