Abstract : This program has been aimed at the technology development of near field optical imaging in reflection, transmission and emissive modes using radiation' from Lw to IR. In this contract period, we have designed and constructed an optical near field/shear force microscope capable of 30 nm resolution. This instrument has been used to demonstrate the difference between topographic and materials contrast and enabled us to quantitatively evaluate the character of near field images. We have shown the role that polarization and detector geometry play in reflection near field imaging and quantitatively assessed spatial resolution in near field systems. In addition, we have demonstrated near field imaging of 1.3um wavelength radiation and near field printing of LIV radiation at close to A/10 resolution. (MM)
