Abstract
We present a method using an ordinary color camera to characterize nanostructures from the visual color of the structures. The method provides a macroscale overview image from which micrometer-sized regions can be analyzed independently, hereby revealing long-range spatial variations of the structures. The method is tested on injection-molded polymer line gratings, and the height and filling factor are determined with confidence intervals similar to more advanced imaging scatterometry setups.
