本文研究了内窥式散斑类共聚焦系统(Endoscope-based speckle quasi-confocal system,EBSQCS)的层析能力。从散斑类共聚焦显微镜(Speckle quasi-confocal microscope,SQCM)成像原理出发,详细分析了内窥镜光学结构对散斑类共聚焦显微镜散斑场波动的影响规律,推导了内窥镜光学结构与内窥式散斑类共聚焦系统轴向分辨力的关系。实验测得了基于光纤束的内窥式散斑类共聚焦系统的轴向分辨力曲线。选用放大倍率4倍,光纤直径5μm的内窥镜系统的内窥式散斑类共聚焦系统轴向分辨力曲线的全峰半高是散斑类共聚焦显微镜的2.3倍,与理论计算值相符。实验结果表明内窥式散斑类共聚焦系统具有很好的轴向层析能力。
In this paper, the chromatographic ability of endoscopic-based speckle quasi-confocal system (EBSQCS) was studied. Based on the principle of Speckle quasi-confocal microscope (SQCM) imaging, the influence of endoscopic optical structure on speckle confocal microscope speckle field fluctuation was analyzed in detail. The optical structure of endoscope Relationship with axial resolving power of endoscopic speckle confocal system. The axial resolving power of endoscopic speckle confocal system based on fiber bundle was experimentally measured. The full-peak half-height of the endoscopic speckle confocal system of an endoscope system with magnification of 4 times and fiber diameter of 5 μm is 2.3 times that of a speckle confocal microscope, which is consistent with the theoretical calculation . Experimental results show that endoscopic speckle confocal system has good axial chromatographic ability.
