Abstract
An optical method and device for detecting surface and structural defects of a traveling hot product, such as flat metal products during hot rolling, is disclosed. The optical method includes using images of the product from a camera and formed for one part by light for which the wavelength is in the infrared region and for another part by light for which the wavelength is in the visible spectrum. Detection of the images is provided by several linear sensors, each of them being associated with the detection of one image, each located in a different focal plane associated with each wavelength range so as to obtain superposable images. The light forming a portion of the images is sent onto the surface of the traveling product.
