ABSTRACT:
A profile measurement apparatus using radiation is disclosed which has three radiation sources and three arcuated multi-channel radiation detectors corresponding to the radiation sources. A rolled steel sheet or strip is conveyed between the radiation sources and the radiation detectors. The sector-shaped radiation beams respectively are radiated by the radiation sources to partially pass through the strip and to respectively incident on the corresponding radiation detectors, which produce profile signals corresponding to the intensities of the incident radiation beams. A microprocessor produces an image signal indicating the sectional shape of an irradiated linear area throughout the entire width of the strip in accordance with the profile signals and causes the display device to display the sectional shape. A mono-channel radiation detector is disposed near the multi-channel radiation detectors to constantly measure a partial thickness of the central portion of the strip.
