Abstract

Near field scanning optical microscopy of thin birefringent samples is described. The system utilized is the linear polarizing near field microscope, resulting in a pure birefringence image of the sample. The sign of the birefringence is also preserved. Two specific classes of sample are studied. These include thin sections of Kevlar fibers, and polymer dispersed liquid crystals. Results are correlated with simultaneously obtained topographic images. Based on experimental observations, the relative strength of the optical indices of the structures is determined
