Abstract

A Non-destructive Test(NDT) for steel cord conveyor belts was developed by using an X ray detector array. The principle of X-ray NDT was introduced and a collimator was used to eliminate the X-ray scattering.An acquisition circuit for multi-channel parallel data was designed to achieve real-time data acquisition. The reason for pixel non-uniformity of the linear array detector was discussed and an algorithm to correct the pixel non-uniformity was established.Then a three-segmented correction algorithm with less computation and better correction effect was proposed based on the response model. Experiments show that the spatial resolution of the image is 1.0 mm1.5 mm and the non-uniformity of the image is below 2.57% for a steel cord conveyor belt with a width of 2 m and a speed of 3 m. Obtained image shows a good gray contrast

and its gray level difference for a 0.5 mm thick steel is about 13.The new NDT has achieved the real-time online monitoring function

and has advantages of intuitive

clear and so on compared with the tester designed by electromagnetic monitoring principles.
