  • Patent number: 11036067
    Abstract: Imaging systems may include tunable polarization filters. A tunable polarization filter may be integrated directly into an image sensor package. For example, the tunable polarization filter may serve as cover glass for the image sensor package. Tunable polarization package glass may be incorporated into image sensor packages that have air gaps between the image sensor and the cover glass or that have transparent adhesive between the image sensor and the cover glass. The tunable polarization layer may be controlled at a global level, at a sub-array level, or at a pixel level. In some cases, the tunable polarization layer may be a tunable polarization filter. In this example, the direction of the polarization filter is tuned. In other cases, the tunable polarization layer may be a tunable polarization rotator. In this example, the tunable polarization layer selectively rotates the polarization of light that passes through the tunable polarization layer.
