Original Abstract

Optical microscopy with local probe in the near field has several advantages against other microscopy types. Main advantages are: easy use, minimal preparation of sample and possibility to get some extra information about sample. There are two basic modes: reflection mode and transmission mode. For sample surface topography measuring fiber quartz system based on shear forces between the tip and sample is used. Topography of sample is important because it allows to keep the distance between the tip and the sample surface constant and this is necessary for increasing the signal to noise ratio. As a probe is being used a metal coated optical fiber taper. During the scanning it is possible to get some extra information. In the case of reflection mode microscope configuration it is local reflection of sample. This characteristic of sample allows specifying some defects of the structure.
