Monocular Metasurface Camera for Single-Shot Multi-Dimensional Imaging

Cameras play vital roles in emerging applications such as augmented reality and autonomous driving. Nontheless, conventional cameras can only acquire light intensity in two dimensions. In order to further obtain the depth, polarization, and spectral information of the target object, it is often required to use bulky and expensive instruments. Metasurface is composed of an array of optical antennas that can manipulate the amplitude, phase, polarization, and spectrum of light at the subwavelength scale. By replacing conventional diffractive of refractive elements with metasurfaces in imaging systems, one may be able to build optical sensors for high-performance multi-dimensional imaging with a low size, weight, and power. In this talk, I will present our recent progress towards this goal.
