The influence of tilted phase on the focal switch is also studied.
着重研究相位倾斜对焦开关现象的影响。
It investigates the focal switch phenomenon of a tilted phase L-G beam passing through a system with the aperture and lens separated.
研究了相位倾斜l - G光束通过光阑——透镜分离系统的焦开关现象。
It is shown that the influence of astigmatism on the behavior of the focal switch is the relative transition height but not the turning point, where the focal switch can take place.
研究表明：像散对焦开关行为的影响表现在相对跃变量上，而不是焦开关出现的临界位置。
