摘要

针对光栅靶中存在的标校问题,采用了光电坐标传感器,详细分析了坐标传感器的原理；构建了光电开关模型,回避了光电管亮度和发射角的一致性问题,并对坐标传感器进行了线性化分析和校正,取得了良好的改善效果.通过实验证明传感器的设计方案优化、参数选取合理、设计指标实用,具有使用安全、成本低的优点,有效提高了报靶的测试精度.%Aiming at the calibration problem existing in the grating target,photoelectric coordinate sensors are designed and applied. By describing the principle of photoelectric coordinate sensors in detail,photoelectric switch model is set up. The scheme avoids the requirements which ask for the radiation brightness and the emission angle to be uniform. Experimental results proved that the scheme of the coordinate sensor is feasible and the parameters selected are reasonable. The design has the advantages of easy making,high precision and low cost. The shot indicating precision is effectively improved.
