    • In a method for detecting impurities in a transparent material, the material (2) is scanned line by line and the light transmission through the material is measured and compared with a reference value. If the transmission value at one point of the material is in a predetermined relation to said reference value, indicating the occurrence of impurities, the light transmission is studied in an area around the measured point for this transmission value in order to determine the extent and shape of the impurity, the light transmission values in the central area of the impurity being compared with transmission values measured in surrounding parts of the impurity to determine whether the impurity is of gel type or an impurity of some other type. A system for detecting impurities in a transparent material, which system comprises a camera (6) arranged to scan the material (2) and register light transmitted through the material in the form of pixel values, and a first comparator (8) for comparing said pixel values with a reference value. If a pixel value is in a predetermined relation to said reference value, a signal processor (12) analyses registered pixel values from an area of the material around said pixel value in order to determine a centre for the impurity and compare pixel values in said centre with pixel values in the surrounding parts of the impurity to determine whether the impurity is an impurity of gel type or an impurity of some other type.
    • 在用于检测透明材料中的杂质的方法中,材料(2)被逐行扫描,并且通过材料的光透射被测量并与参考值进行比较。 如果材料的一个点处的透射值与所述参考值成预定关系,指示杂质的出现,则在该透射值的测量点周围的区域中研究透光率,以便确定该透射值的程度和形状 将杂质的中心区域中的透光率与在杂质的周围部分测量的透射值进行比较,以确定杂质是凝胶型还是其他类型的杂质。 一种用于检测透明材料中的杂质的系统,该系统包括布置成扫描材料(2)并以像素值的形式记录通过材料透射的光的照相机(6),以及用于将所述 具有参考值的像素值。 如果像素值与所述参考值成预定关系,则信号处理器(12)从围绕所述像素值的材料的区域分析已注册的像素值,以便确定杂质的中心并比较所述中心的像素值 在杂质的周围部分具有像素值,以确定杂质是否是凝胶类型的杂质或某种其它类型的杂质。
