Abstract

In confocal scanning imaging system, using apodization masks can improve the system resolution. A mask based on circle grating function with different spacing is presented and made, which is simple and easy to practically make and apply. The experiments of using a mask are performed in a reflection-mode fiber confocal scanning microscope. The intensity response curves in transverse and axial direction of this system are given. A sharp straight edge of a flat object is measured. And the 2D image of a biological organism is also given. The results demonstrate that adding this apodization mask does not reduce the axial resolution while improve the transverse resolution.
