【摘要】 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。着重研究相位倾斜对焦开关现象的影响。研究结果表明,相位倾斜影响了相对焦移量、相对跃变量和焦开关发生的位置,同时也影响焦开关出现时截断参数的取值范围。另外,截断参数也会影响焦开关发生的位置。更多还原

【Abstract】 It investigates the focal switch phenomenon of a tilted phase L-G beam passing through a system with the aperture and lens separated.The influence of tilted phase on the focal switch is also studied.The results demonstrate that the tilted phase affects not only the relative shift and the transition height rather than the turning point,but also affects the truncation parameter region when the focal switch appears.In additon,the truncation parameter affects the turning point.更多还原
