摘　　要：根据双光路红外光电转换原理 ,叙述了一种用于检测非透明件直径的双光路动态直径自动控制技术的基本原理及结构特点。该仪器不仅适用于检测圆柱体直径 ,还适用于检测箱体的长度、宽度 ,而且在使用过程中不易受外来杂光散光的干扰。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.
