摘要: 将无衍射光技术与传统的莫尔条纹干涉技术相结合,并且应用于光电瞄准系统中,从基本理论和原理实验上研究了一种新型的机载瞄准方法,提出了相应的瞄准跟踪技术.该方法根据无衍射光与目标圆环光栅之间迭加产生干涉图形的偏移和变化量,通过调整机载光电系统,达到精密瞄准之目的. 所发展形成的新型瞄准跟踪技术,不仅有助于提高瞄准吊舱的动态响应速度、跟踪精度及其稳定性,进一步提高导弹的横向命中率,而且可以增强进攻过程中的精确打击能力,为新型机载武器装备的研究提供技术储备.Abstract: The non-diffracting technique was combined with the traditional Moire fringe interference technique and was applied firstly in the airborne opto-electronics system. A novel airborne aiming method was developed in basic theory and its principled experiment, the relevant aiming and tracking techniques were also proposed. This method could be carried out by adjusting the airborne opto-electronics system according to the deviation and variation of the interference patterns caused between the non-diffracting beam and objective circular gratings.The accurate aiming purpose could thus be completed. The newly developed aiming and its tracking techniques would not only be helpful to improve the dynamic responsibility, tracking accuracy and the reliability of the aiming pods, but also enhance the attacking ability with high accuracy during the offensive process. Therefore it can be used to provide the technical store for the new airborne weapon and its equipment.
