    摘要: Described are techniques for obtaining spectroscopic information from sub-micron regions of a sample using a probe microscope. The current invention uses the response of an AFM cantilever at a plurality of frequencies to substantially reduce the impact of background absorption away from the sub-micron region of interest. This innovation substantially improves the quality of spectra for top down illumination of samples that are not suitable for bottoms up illumination of the prior art.
