给出了在反射式光纤共焦扫描成像系统中 ,利用变迹术提高系统分辨率的原理 ,并做了相应的对比实验 .在加入变迹掩模后 ,系统对物体的成像响应曲线、物体直边边缘展宽量都有所改善 .实验数据证明 ,改变光瞳函数可以提高系统的横向分辨率 ,同时不降低系统的纵向分辨率 . The principle of using the apodization technique to improve the system resolution in the reflective fiber confocal scanning imaging system is given and the corresponding comparison experiments are made.After adding the apodization mask, the imaging response curve of the object, the object The amount of edge broadening in the straight edge has been improved.Experimental data show that changing the pupil function can improve the horizontal resolution of the system without reducing the vertical resolution of the system.
