摘要
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 .
In confocal scanning imaging system, using apodization can improve the system resolution. The paper presents the principles. The experiments are done in a reflection mode fiber confocal scanning microscopy with the mask, the intensity response curves in transverse and axial direction of this system are given. A sharp straight edge of a flat object is measured. The results demonstrate that an apodizated mask does not reduce the axial resolution while can improve the transverse resolution.
