Abstract
Birefringence, arising from locally preferred orientation of molecules or functional groups in polymeric and related materials has been obse rved in a near-field scanning optical microscope (NSOM) at suboptical samples, demonstrating the utility of birefringence observations in NS OM. We present data acquired from thin sections of a partially ordered polymer fiber (Kevlar) and a polymer dispersed small-molecule-liquid- crystal composite.
