[0002] Laser scanning measurement technology utilizes the excellent focus characteristics of the laser light source and uses the principle of fast flying spot light scanning measurement to achieve precise measurement of geometric quantities such as diameter and thickness. Its application system is an important technical means for non-contact precision measurement and control. This technology has been effectively applied to the measurement and control of the outer diameter, thickness, width, etc. in the laboratory measurement and testing, steel mills / wire factories, and optical (electrical) cable production processes. It has the characteristics of high precision, fast speed, safety and reliability. It is an important measurement and monitoring method in the above-mentioned production fields. The existing high-precision laser diameter measuring device is relatively large in size and cannot be carried. The opening of the measurement area is large, and the error caused by the measurement of small workpieces is relatively large.
