New infection of truncation parameter on focal shift and focal switch is investigated when studying laguerre - gaussian ( l - g ) beams passing through an aperture - lens separate optic system
摘要以拉蓋爾高斯（ l - g ）光束通過光闌透鏡分離的光學系統為例，研究了截斷參數對焦移量和焦開關的影響。 -
The numerical results show that the appearance of focal switch rests not only on the distance of aperture and lens but also on truncation parameter ; focal switch possibly occurs only when truncation parameter is between its critical maximum and minimum truncation parameters
數值結果表明：焦開關的出現不僅與光闌透鏡分離量有關，還與截斷參數值密切相關；僅當截斷參數取某一上、下限之間的值時，才可能出現焦開關。 -
