Color measurement of glass plates The color of glass plates should be measured. It should be noted, that the colored opaque glass layer is covered from a transparent shiny glass layer and the color should be measured through the transparent glass layer. The challenge is, to avoid that the direct reflection from the surface of the transparent glass layer is influencing the color measurement result. |

Distance measurement to colored car glass The distance to colored car glass should be measured. It has to be taken into account, that due to the fact, that several measuring points at the glass surface are necessary, the space for the respective measurement device, especially the frontend is limited. |

Spray-jet control during the glass bottle coating process in the pharmaceutical industry During the production of glass bottles for the pharmaceutical industry the inner surface must be coated with a certain chemical film, which makes the bottles diffuse. At this crystals will be sprayed through the bottle neck with a nozzle into the bottle. During this process, the bottles have still a temperature of a few hundred centigrade. |

Position measurement of a transparent glass plate Glass handling machines must be informed not only about the distance of a glass plate but also about the edge position of a glass plate. However the detection of the edge of a transparent glass plate is not so easy, especially if there is nearly no phase on the edges. The direct reflection rate of visible light on a standard glass surface is normally approximately 4% and with the additional reflection of the second surface around 8% of the light will be reflected. |

Distance measurement on transparent glass plates During the handling process of glass plates the distance of the glass surface must be controlled. As during the beveling process the glass plate must be positioned in a way that the glass edges can be feed symmetrically into the abrasive block of the grinding machine, otherwise the phases on both sides of the glass plate are different. Due to the fact, that the glass surface delivers nearly no diffuse reflected light but only direct reflected light, a standard laser displacement sensor cannot be used. |

Detekcija prozornih oz. svetlečih površin na matiranem steklu Med proizvodnjo matiranega stekla se lahko na steklu pojavijo majhne površine oz. madeži, ki so bodisi prozorni ali bleščeči in te je potrebno zaznati. Premer le-teh, ki ga je mogoče zaznati, se začne pri približno 3 mm. Detection of glossy regions on a matt-finished glass plate During the production of matt-finished glass plates the matt-finished surface must be controlled particularly with regard to small glossy spot. The glossy domains which should be detected are starting with a diameter of approximately 3 mm. |
