    摘要： A method (and system) for the identification of defects in transparent slabs comprises at least the phases of supply of at least one transparent slab to be inspected; acquisition of at least one image of at least one portion of the slab along an acquisition line; identification of at least one defect in the slab depending on the acquired image; at least one emission phase of at least one light radiation transmitted inside the slab along an emission line substantially transverse to the acquisition line and adapted to be incident with at least one defect in the slab in order to identify the position thereof, the light radiation incident with the defect being diffused by the latter at least in part outside the slab.

    摘要： A method and/or system is provided for detecting inclusions (e.g., nickel sulfide based inclusions/defects) in soda-lime-silica based glass, such as float glass. In certain example instances, during and/or after the glass-making process, following the stage in the float process where the glass sheet is formed and floated on a molten material (e.g., tin bath) and cooled or allowed to cool such as via an annealing lehr, light is directed at the resulting glass and reflection of various wavelengths (e.g., red and blue wavelengths) is analyzed to detect inclusions.

    摘要： A method and/or system is provided for detecting inclusions (e.g., nickel sulfide based inclusions/defects) in soda-lime-silica based glass, such as float glass. In certain example instances, during and/or after the glass-making process, following the stage in the float process where the glass sheet is formed and floated on a molten material (e.g., tin bath) and cooled or allowed to cool such as via an annealing lehr, visible light from an intense visible light source(s) is directed at the resulting glass and thermal imaging is used to detect inclusions based on a temperature difference between the inclusions and surrounding float glass. In another example embodiment, inclusion detection may be performed without exposure of the glass to light from a light source(s). Inclusions and surrounding glass may cool at different rates and be at different temperatures just prior to and/or after an annealing lehr, and a difference in residual temperature between inclusions and surrounding glass may be detected via thermal imaging and identified to identify inclusion(s).
