Modal analysis of liquid-solid coupling liquid lens
SPIE Proceedings, 2014Liquid lens of fast focusing is valuable to be researched for the application in instruments of miniature. According to many researchers achievement in this field, the fast focusing mechanism of liquid lens is firstly present. Then the oscillation modes of the liquid-solid coupling liquid lens in different capillary tube cases are analyzed in this ...

Liquid Crystal Lens of Two Liquid Crystal Layers
Molecular Crystals and Liquid Crystals, 2004Liquid crystal lenses(LCL)of two liquid crystal(LC)layers with parallel and orthogonal optic axes are built. The LCL of two LC layers with parallel optic axes is designed to obtain larger focusing power, and that with orthogonal optic axes is to focus light wave of arbitrary polarizations.

Elliptical cylindrical liquid lens
The Journal of the Acoustical Society of America, 1973The problem of focusing a pressure wave by a thick, elliptical cylindrical liquid lens has been treated in a rigorous manner. The size of the lens is of the order of or slightly greater than the wavelength of the incoming acoustic signal. Detailed computation has been carried out for a representative case in which a liquid lens with an index of ...
