We named the resulting technique Near-Field Scanning Optical Microscopy, or NSOM. In parallel with these developments, Dieter Pohl at IBM Zurich developed a similar idea, originally called Optical Stethoscopy and later called Scanning Near-Field Optical Microscopy, or SNOM. Truth be told, approximately fourteen years before our paper and Dieter ...George Zorinyants, O. Kurnosikov. Apertureless magneto-optical near-field microscopy is developed for studying sub-picosecond spindynamics at nanometer spatial scale. Polarization modulation and tip vibrations are implemented. Polarization responsivity of the tip-induced scattering is demonstrated using polarization modulation and tip vibrations. Near-field scanning optical microscopy (SNOM) techniques exploit Synge's principles, and rely thus on the optical interactions that occur between the light emerging from a subwavelength aperture or scattered/enhanced by a subwavelength tip and an object in its immediate vicinity. Apertureless scanning near-field optical microscopy (ASNOM ...

Abstract. A trapped-particle near-field scanning optical microscope is constructed by use of submicrometer- or micrometer-sized metallic particles (gold and silver) to increase scattering efficiency.
