Imaging through plasmonic nanoparticles
Abstract
How is an image transmitted through a material consisting of subwavelength structures? We use two distinct methods to obtain quantitative answers to that question. The first, structural similarity index, is a method related to human perception, initially developed to quantify transmitted image quality following image compression in digital image transmission systems. The second method treats the medium as an optical component itself, where we determine the spatial frequency content of the image transmitted by the medium. This study opens the door to analyzing images transmitted through particulate media that absorb and/or scatter light, which applies generally to imaging systems whose components are composed of subwavelength structures, such as those composed of random particulates or nanoengineered flat-optics metasurface lenses.
