Zusammenfassung: | The invention discloses double-laser scanning equipment which is characterized in that a laser emitter is used for emitting a first scanning line and a second scanning line; the first scanning line is emitted after passing through a first emergent light polarizing film, a first total reflection mirror, a first curved surface reflection collecting mirror and a laser deflector and is used for scanning an identified and read object, and reflected laser is transmitted to a decoding unit through a first incident polarizing film and a first photoelectric converter after passing through the laser deflector and the concave surface of the first curved surface reflection collecting mirror in sequence; the second scanning line is emitted after passing through a second emergent light polarizing film, a second total reflection mirror and the laser deflector and is used for scanning the identified and read object, and the reflected laser is transmitted to the decoding unit through a second incident polarizing film and a second photoelectric converter after passing through the laser deflector and the concave surface of the second curved surface reflection collecting mirror in sequence. According to the double-laser scanning equipment, the scanning speed of the equipment can be increased to be twice that of original laser scanning equipment, so that the decoding speed is greatly increased and the user experience is improved. |
