| Abstract: | The several optical circuits using laser triangulation technique for distance measurements are compared,and a new method of light source scan laser triangulation technique for distance measurements is presented,and the principle of laser triangulation for distance measurement is introduced,and the measurement system is designed,and the influencing factor of system accuracy is analyzed.Theory shows that the resolution can up to 1.5×10(-5)m.The result of experiment shows that this system is very useful,the measurement rang from(0 mm~10 m) is suitable for industrial production. |
