摘要： Disclosed herein is various shared-aperture camera systems and calibration methods. One particular shared-aperture camera system includes a polarization imaging device including: an aperture; a first metasurface configured to diffract incident light going through the aperture such that a first polarization of incident light diffracts in a first direction and a second polarization of the incident light diffracts in a second direction; an image sensor; and a planar diffractive lens including a second metasurface configured to focus the first polarization of incident light diffracted in the first direction onto a first portion of the image sensor and focus the second polarization of incident light diffracted in the second direction onto a second portion of the image sensor.

摘要： Meta-surface devices may be advantageously used for miniaturization, planar and thin film, high spatial resolution, and dense integration into optical devices. They have the potential to be used for steering a beam propagation direction, shaping wave-front light, and imparting information for application such as sensing, imaging, light detection, and ranging. However, meta-surface devices may have poor overall efficiency when compared with traditional optical devices. Embodiments of this disclosure relate to meta-surface devices including a pattern of high-index pillars with a low-index coating. Advantageously, the low-index coating may improve optical efficiency of the meta-surface devices which may make these meta-surface devices suitable for a variety of applications.
