Polarized Light in Liquid Crystals and Polymers

Front Cover
John Wiley & Sons, Jan 2, 2007 - Science - 480 pages
Polarized Light in Liquid Crystals and Polymers deals with the linear optics of birefringent materials, such as liquid crystals and polymers, and surveys light propagation in such media with special attention to applications. It is unique in treating light propagation in micro- and nanostructured birefringent optical elements, such as lenses and gratings composed of birefringent materials, as well as the spatial varying anisotropic structures often found in miniaturized liquid crystal devices.

Page 1 - ... analyzed with a quarter-wave plate and a linear polarizer. Any combination of the two is called a polariscope. Uses. A major industrial use of polarized light is in photoelastic stress analysis. Models of mechanical parts are made of a transparent plastic such as Bakelite, which becomes birefringent when stressed. Normal forces are applied to the model, which is then examined in a polariscope between crossed polarizers. Unstressed regions remain dark; regions under stress rotate the polarization...
