激光多点点火系统自诊断检测技术研究

Study on Build-in Test Technology for Laser Multi-point Initiation System

针对激光多点点火系统可能因传输光纤折断、端面污染或缺陷、光开关损坏等问题而出现系统光路不完整,致使系统可靠性降低的问题,通过采用双光纤双波长工作模式,建立了具有自诊断检测功能的激光多点点火系统,确立了检测装置对检测激光接收效率与系统光路状态之间的关系,从而实现了激光多点点火的同步定量检测。

Aiming at some problems existed in laser multi-point initiation system, such as fiber disjunction, contamination or disfigurement on the ends of fibers and fault in optical switch, which may result in incompleteness of optical system, and reduce the reliability of laser initiation system, a laser multi-point initiation system with build-in test function was established by dual-fiber dual-wavelength model. The relation between receiving efficiency of test device for test laser and the optical state of system was obtained. As well as the synchronous test for laser multi-point initiation was achieved.
