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.
