Abstract
An imaging system is provided. The imaging system includes a sample to be scanned by the imaging system. An absorbance modulation layer (AML) is positioned in close proximity to the sample and is physically separate from the sample. One or more sub-wavelength apertures are generated within the AML, whose size is determined by the material properties of the AML and the intensities of the illuminating wavelengths. A light source transmits an optical signal through the one or more sub-wavelength apertures generating optical near-fields that are collected for imaging.
