Optical readers and methods employing polarization sensing of light from decodable indicia
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.
