Laser light section measuring

Laser light section measurement is a core technology for high‑performance long product production. The method projects laser lines onto billets, sections, and other long products, while cameras capture the reflected light to calculate precise distance values. This enables the full contour to be measured contactlessly and with high resolution. Unlike conventional shadow‑based systems, light section measurement captures the true cross‑section rather than isolated dimensions, even for complex profiles. High sampling rates, short exposure times, and fully synchronized sensors ensure reliable measurement at high rolling speeds and under harsh mill conditions. The result is accurate geometry data that supports stable rolling processes, reduced scrap, and consistently high product quality.
