Laser Doppler speed and lengths measuring devices in class accuracy ± 0.1 % rate are perspective for measurement of hot rolled steel. In this paper, the optimal structure of the processing module based on modern high-performance signal processor TMS320C6713 is proposed for the processor of the laser reverse Doppler speed and length measuring system for hot rolled steel (LDA-M). This structure is implemented in the developed processing module. The system of processing module and the software as a part of the LDA allows using FFT algorithms, interpolation FFT results and optimal filtering of measurements to calculate accurately the speed and length of the hot-rolled steel products in the industry. Illustrative charts with LDMS results in different conditions, including those in steel mills, are provided.
