摘要
在简要介绍激光火工品系统检测技术发展的基础上,综述了激光火工品系统检测中微弱光信号的探测原理与处理方法以及这些方法的应用;通过对锁相放大器频谱迁移法、谐波小波频域提取法、双路消噪声法以及放大与滤波电路法的比较和分析,得出锁相放大器频谱迁移法和放大与滤波电路法可用于激光火工品系统检测的结论.
The development of automatic testing technology in laser initiating system was introduced and the theory and method of feeble-optical-signal detection used in the automatic testing systems for laser initiating system were discussed. Through both the comparison of several methods, including spectrum relocation method of phase-lock amplifier, harmonic wavelet extraction method, double- channel de-noising method, and the comparison of different kinds of amplification circuits and filter circuits, the conclusion was drawn that the spectrum relocation method based on phase-lock amplifier could be better suitable for automatic testing technology in laser initiating system.
