Abstract:

The problem studied was the detection of sub-wavelength detail by scanning near-field microscopy, using a vibrating knife-edgestylus rather than an aperture probe. A related problem was phase detection of an optical field by such scanning, not necessarily in the sub-wavelength region. MOST IMPORTANT RESULTS 1 Demonstration of one-dimensional principle of operation 2 Demonstration of non sub-wavelength two-dimensional microscope with vibrating knife edge corner 3 Demonstration of non sub-wave length two-dimensional tomographic microscope with vibrating knife edge 4 Analysis and simulation of evanescent wave to plane wave conversion 5 Analysis and demonstration of phase measuring properties of one-dimensional vibrating knife edge microscope.
