OPTICAL IMAGING OF NANOSTRUCTURED SUBSTRATES

摘要

A method of imaging phenomena that occurs on a surface of a substrate includes contacting a fluid with a top surface of the substrate, and imaging phenomena that occurs on the top surface of the substrate by observing the substrate through polarized light in the absence of a liquid crystal after the liquid has contacted the top surface of the substrate. The top surface of the substrate has an anisotropic topography, and the wavelength of the polarized light is larger than the anisotropic topography of the top surface of the substrate.
