“飞行光学”焦移研究

Research on the Focal Shift in Flying Optics

基于焦移传输理论 ,推导了“飞行光学”中焦移、相对焦移的表达式 ,分析了“飞行距离”、瑞利长度和聚焦镜焦距对“飞行光学”中焦移。

Base on the propagation theory of focal shift, the analytical expression of focal shift and relative focal shift were deduced. The effects of flying distance, Rayleigh range and the focal length of focusing lens (or mirror) on focal shift were also discussed.
