  • Optical readers and methods employing polarization sensing of light from decodable indicia
    Patent number: 9262661
    Abstract: A method for decoding decodable indicia includes sensing the polarization of light from a plurality of orientations in connection with the decodable indicia, and controlling at least one of energizing an illumination subsystem based on the sensed polarization indicating a generally randomly polarized light, and inhibiting energization of the illumination subsystem based on the sensed polarization indicating a generally linearly polarized light. One or more images are captured, and an attempt is made to decode the decodable indicia using at least one of the one or more images.
    Type: Grant

    Date of Patent: February 16, 2016
    Assignee: Honeywell International, Inc.
