光电坐标传感器在光幕靶中的应用

摘要

Against the problems of calibration scheme existing in automatic photoelectric target-scoring system,problems of sensitivity consistency of photoelectric receiver and mass data collection with high speed existing in infrared optical screen,LED luminescent tube with large radiation angle has been adopted.With photoelectric switching circuit and high speed sampling and holding circuit designed,photoelectric coordinate sensors based on photoelectric switch and sampling resistance network have been realized,increasing detection sensitivity and systemic consistency,reducing difficulty and cost of system design.It is validated that this method has higher precision with better prospect of application.%针对光电报靶系统的标校问题，以及可见光光幕靶光电接收器检测灵敏度的一致性和与海量数据的高速采集问题，采用大发射角的LED发光管，设计了光电开关电路和高速采样保持电路，实现了基于光电开关和取样电阻网络的光电坐标传感器，提高了系统的检测灵敏度和一致性，降低了系统设计的难度和成本。试验证明：该方法精度较高，具有良好的应用前景。
