The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

The Study of Laser-Induced Intensity Gratings in Azo-Dye Doped Liquid CrystalsLin, Hsin-chia 12 July 2004 (has links)
The laser-induced holographic grating technique was employed to study the dynamic of the intensity grating formation in the azo-dye doped liquid crystals. The liquid crystal material in this study has several mesomorphic phases: smectic C, smectic A, and nematic. The first order of diffraction in the mesomorphic phases have been investigated by changing the concentration of dye, the polarizations of the writing beams and the probe beam

The Study of Holographic Grating on Azo-Dye Doped in Multi-phases LCsChang, Chih-Hung 27 July 2005 (has links)
The laser-induced holographic grating technique was employed to study the dynamic of the intensity grating formation in the azo-dye doped liquid crystals. The liquid crystal material in this study has several mesomorphic phases: Smectic C, Smectic A, Nematic and Isotropic. The first order of diffraction in the mesomorphic phases have been investigated by changing the polarizations of the probe beam.
