Abstract
Digital and optical image processing techniques have become ubiquitous and algorithms and optical methods for noise reduction, edge detection, image enhancement and object identification are widely used. Digital approaches, however, cannot access the phase of a field and require energy and time which scale with the amount of data acquired, but conventional optical methods are bulky, prohibiting their use in compact devices and platforms such as smartphones and nanosatellites. This presentation discusses theoretical aspects and experimental results demonstrating the use of metasurfaces and other compact nanophotonic devices for direct spatial frequency filtering of images.
