【Abstract】 Acording to the pinciple of opto-electrical transform of double infared optical beams, this paper describled the basic principle and design’s features of dynamically auto-controling diameter technology with double optical beams. The system not only inspected the diameter of cylinder, but also inspected the length and width of box, and avoided the disturb of light in confusion during using.更多还原
