Abstract:

This contract studied the acousto-optic effect which occurs in nematic liquid crystals when excited by acoustic waves including extension and testing of the streaming model developed by C. F. Hayes. The results indicate that the model is valid. Equations have been solved giving both the magnitudes and patterns of the induced flows. These results have been tested experimentally and agree quite well with the theory.
