METHOD AND APPARATUS FOR PERFORMING APERTURELESS NEAR-FIELD SCANNING OPTICAL MICROSCOPY

摘要

A microscope for performing apertureless near-field scanning optical microscopy on a sample comprising a means for mounting a sample; a scanning probe; means for illuminating the sample with light along optical axes from at least two illumination angles relative to an imaginary line connecting the probe and the sample; means for enhancing the electric field of light in a region of the sample with the probe; means for scanning the sample in a plane perpendicular to an imaginary line connecting the probe and the sample; means for moving said sample along said imaginary line to maintain a nearly constant distance between the probe and the sample; and means for collecting light scattered, emitted, or transmitted from the sample.
