Abstract
A device for detecting surface flaws of rapidly moving metal strip in rolling mills includes a lens which scans the sheet material surface and a camera tube which converts optical images of the lens into electrical values. These values are stored in a magnetic storage and are called out to be converted and displayed on an image reproducing device as a visible image. At least one image amplifier or image converter tube is interposed between the lens and the camera tube and includes an electronic speed shutter.
