According to the hydraulic transmission principle, a device for fabricating largecone Angle near-field optical fiber probe by means of dynamic chemical etching is developed.
基于液压传递原理，设计出一种用动态化学腐蚀法制备大锥角近场光纤探针的装置。

Probes of various structures, such as largecone angle and short taper or multi-taper, can be formed with the combination of the static and dynamical chemical etching methods.
利用此法可制备出尖端锐利、大锥角或多锥体等各种结构的光纤探针。

The main reason is the radon space data of scanned object is not complete, which will result in the image artifacts when using FDK algorithm to reconstruct with moderate or largecone angles.
