摘　　要：研究一种了基于荧光光波导的新型探测光幕。将硅光电二极管粘附于荧光薄片,结合4个线性激光器形成一个矩形探测区域光幕。目标物体进入光幕时,产生的阴影投射在荧光薄片上,运用一个简单的数学算法将投射在荧光薄片上的阴影中心位置计算出,进而根据中心位置将目标物体的位置快速探测出。利用C编程及MATLAB软件对装置进行仿真,验证了装置的可行性。A new detective optical screen based on fluorescence waveguides has been studied. With four linear lasers, a rectangular detective optical screen can be made by attaching silicon photodiodes to fluorescent stripe. When an object enters the active area, shadows are formed on the fluorescent stripes. A simple calculation algorithm can be used to obtain the central position of the shadow on the fluorescent stripe, and then accordingly the position of the object can be detected fast. The device has been simulated through C programming and MATLAB to verify its feasibility.
