In near-field microscopy, the Karhunen-Loeve transform could be an efficient tool for separating actual information from noise without reducing the spatial frequency band. Both experimental data and simulations are analyzed using such a signal processing. !16Daniel Charraut...
We have observed near-field optical images of phase change marks and evaluated the readout signals including the optical near-field. Samples were composed of multilayered structures on glass substrates. Crystalline marks were recorded by a focused laser beam with an optical microscope in the as-dep...
A new super-resolution method, entitled Near-field Projection Optical Microscopy (NPOM), is presented. This novel technique enables the imaging of nanoscale objects without the need for surface scanning, as is usually required in existing methods such as NSOM (near-field scanning optical microscope...
