Description:

Metasurfaces offer optical engineers unprecedented control over the degrees of freedom of light. These single-layer, lithographically defined structures can dictate light’s flow, dependent on its incoming polarization, angle, or color. We report on the integration of a functional, polarization-splitting metasurface layer on a near-infrared (NIR) image sensor, demonstrating high-quality snapshot polarimetric imaging for biometric applications, where polarization is used as a discriminating signal for spoof detection.
