Light contrast scanner for identifying marks |
摘要 |
The sensor has a light transmitter (2) with spatial adjacent light emission diodes to emit transmitting light of red, green and blue wavelength range through a transmitting lens. A light receiver receives reflected or remitted transmission light. A mixing unit intermixes different color portions of the transmission light and formed by a light conductor (22). The length of the conductor amounts to 3-5 times the lateral dimension. |
