| 摘 要： | 针对激光起爆系统可能会出现起爆光路的不完整从而影响正常的起爆,设计了激光起爆系统自相关检测和互相关检测两种不同的光路完整性检测结构,并对两种结构进行了理论分析和对比.结果表明,自相关检测结构可以检测到激光起爆器回馈光纤中回波信号的最小功率为100nW,互相关检测结构能检测到激光起爆器回馈光纤中回波信号的最小功率为0.1...

| Abstract: | In order to escape unsuccessful initiation from non-integrity of the optical path in a laser initiation system,both autocorrelation detection and cross-correlation detection were designed and compared.The experimental results show that the lowest detectable power of echo signal of laser initiator feedback fiber is 100nw for autocorrelation detection,0.1mw for crosscorrelation detection respectively.When the laser power is less than 0.2mw,the integrity of the optical path can be detected with cross-correlation detection,but cannot with autocorrelation detection. |
