摘要

我们首次成功展示了使用电可调谐有源超表面进行三维(3-D)深度扫描，这是一种具有活性铟锡氧化物(ITO)层的等离子体谐振器阵列。我们的有源器件通过使用两个单独的偏置控制，在0到360°范围内独立控制振幅和相位，从而使反射光束具有正的边模抑制比。对于移动和汽车应用的小型高速3D深度传感来说，这些都是非常有希望的结果。

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 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.
