基于透光率表征的光电式枪口烟检测系统分析研究

针对枪口烟具有流动性、瞬态性以及难以捕捉等特性,设计了一种枪口烟定量测试系统,该系统分别测量出激光穿过有烟与无烟时枪口烟雾收集器的感光电压,并计算出透光率表征枪口烟浓度.原理样机的试验结果表明:该系统性能可靠,工作稳定,测试结果准确可信,为枪口烟的测试提供了一种重要的手段.

Research on a Photoelectric Detection System of Muzzle Smoke of Small Arms Based on the Characterization of Light Transmittance

According to the characteristics of mobility, transient effect and uncontrollability, a quantitative detection system of muzzle smoke of small arms was designed, which measures the photosensitive voltages of the penetrating laser through the space of the muzzle smoke collecting box in the states with and without smoke respectively.The calculated light transmittance was used to characterize the smoke concentration of the muzzle smoke of small arms.The prototype was developed.Test results prove that the developed system features high reliability, stable operation and accurate test results, which provides an important method for testing muzzle smoke of small arms.
