Reconfigurable image processing metasurface
In work just published in Nature Communications, a collaboration between University of Melbourne, CUNY, and RMIT University has demonstrated a metasurface that can be switched between edge detection and producing a conventional image. The device integrates a thin film of VO2 that undergoes a phase change at around 68C altering its optical properties opening up applications in remote sensing and biological imaging. A summary of the work can be found in a TMOS blog post here. Cosmos has also covered the work. Story here.
