    • Apparatus for detecting cracks in optically transparent articles e.g vials, comprising a mount for the article, a light source to direct light at a mounted article, an optical detector positioned to receive light from the light source passed through the article and to generate an electronic signal responsive to received light, first and second (analyzer) polarizers such that light from the light source passes through the first polarizer then through the article, then through the second polarizer on its path to the optical detector, with an optical wave plate positioned between the mount and the second polarizer, and an image processing system to process the electronic signal generated by the optical detector and to indicate the presence or absence of a crack in the article supported on the mount. A method of crack detection using the apparatus is also provided.
    • 用于检测例如小瓶的光学透明制品中的裂缝的设备包括用于制品的支架,用于将光引导到安装的制品上的光源,定位成接收来自通过的光源的光的光学检测器 并且产生响应于接收到的光的电子信号,第一和第二(分析仪)偏振器,使得来自光源的光穿过第一偏振器然后穿过物品,然后通过第二偏振器到达光学检测器, 其中光学波片位于底座和第二偏振器之间;以及图像处理系统,用于处理由光学检测器产生的电子信号,并指示支撑在底座上的物品中是否存在裂缝。 还提供了使用该设备的裂缝检测方法。
