【摘要】 根据梯度折射率多模光纤的传输模式,获得多模光纤共聚焦系统的轴向光强分布,说明多模光纤共聚焦系统具有光学层析能力。通过位于电控平移台上的平面反射镜的轴向运动,测量了多模光纤和单模光纤共聚焦系统的轴向光强分布,发现多模光纤共聚焦系统的层析能力约为14微米,对比测量结果证实理论分析的可行性。更多还原

【Abstract】 Based on transmission mode of multi-mode fiber with gradient index,the axial intensity distribution of multi-mode fiber confocal system has been presented,which shows the system has optical sectioning property. With the move of plane mirror on motorized stage along optical axis,the axial intensity distribution of multi-mode and single-mode fiber confocal system have been measured respectively.It is found that multi-mode confocal system has optical sectioning property with about 14 microns.Through the comparison between multi-mode and single-mode fiber confocal system,the theoretic analyse is shown to be feasible.更多还原
