摘　　要：针对探测距离会对光幕系统探测灵敏度产生影响,分别建立弹丸进入系统时遮挡激光产生的光通量变化与系统接收弹丸反射激光功率的数学模型,得到最终弹丸过靶产生的光功率变化的数学模型,根据能够引起系统响应的最小光功率,得出了弹丸处于不同探测距离条件下光幕系统能够探测最小弹丸的尺寸,最后通过实验对数学模型结果进行验证。该研究对于根据所需探测灵敏度设计合理探测靶面,具有重要意义。Mathematical models are established regarding changes in light flux caused by the obstruction of laser beams upon entry of projectiles into the system,as well as the power of reflected laser beams received by the system.By integrating these two fac⁃tors,a comprehensive mathematical model is developed to predict the changes in light power resulting from projectiles passing through the target.Using the minimum light power required to trigger a system response,the minimum size of projectiles that the op⁃tical curtain system could be detected at different detection distances.Finally,the results of this mathematical model are verified through experimental data.This study is of great significance for designing a reasonable detection target surface based on desired de⁃tection sensitivity.
