Electrically Reconfigurable Active Metasurface for 3D Distance Ranging

For the first time, we have successfully demonstrated a 3-dimensional (3-D) depth scan using an electrically-tunable active metasurface, which is an array of plasmonic resonators with an active indium-tin-oxide (ITO) layer. Our active device can steer a beam in reflection with a positive side-mode s...

Description
Summary:For the first time, we have successfully demonstrated a 3-dimensional (3-D) depth scan using an electrically-tunable active metasurface, which is an array of plasmonic resonators with an active indium-tin-oxide (ITO) layer. Our active device can steer a beam in reflection with a positive side-mode suppression ratio by independently controlling the amplitude and the phase from 0 to 360° using two separate bias controls. These are very promising results for small and high speed 3D depth sensing for mobile and automotive applications.
