Rapid, non-destructive and continuous technology for on-line texture determination and corresponding deduction of texture related properties of industrial materials could serve for the instant and uninterrupted quality inspection and control on the production line in modern material industry. High accuracy and high velocity are the two key factors of the on-line measurement technology. Two-dimensional X ray detector can collect very large amount of diffraction data instantaneously, and therefore could be used to capture the necessary pole figure data which could become very limited because of the symmetry and multiplicity of the pole figures. The corresponding accuracy of the texture measurement was increased obviously, while only the important diffraction data were selected and collected if the texture components of material products were known in advance and supposed to have Gaussian forms. The examination process and following texture calculation can be completed very rapidly with satisfied accuracy, which is suitable to the texture examination on stepwise or continuous materials production lines. A further transmission technique was proposed to ensure the representative texture expression in case of inhomogeneous texture through the material thickness. The on-line technologies for texture determination of pure aluminum, AA3104 aluminum alloy as well as interstitial free steel sheets were introduced as examples. It was also attempt to determine the texture related Lankford value of interstitial free steel sheets based on the on-line technology.
