And Finally according to theprogramed algorithms, simulation and experimental stitchings are porformed for testing thealgorithm accuracy. Results show that, the comprehensive errors of theretical andexperimental wavefront stitchings are less than 10~(-6)λand than PV/10 (where PV refering towavefront peak-to-vally value), respectively. Furthermore, experimental research isconducted on the influence of stitching accuracy by sub-aperture overlapping area andstitching modes, with subaperature real-time stitching test for large plano-optic broughtabout.

第三，对编写的算法程序进行了模拟拼接实验和实际拼接实验，测得该算法程序的精度为：理论拼接波面的综合误差小于10~(-6)λ，实际拼接波面的综合误差小于PV／10(PV为被测波面相位峰谷值)；在此基础上，又就子孔径重叠区域大小和拼接模式对拼接精度的影响进行了实验和分析，实现了大口径光学平面的子孔径实时拼接检测。

"Core alignment splicers have long been the preferred method for CATV installations, backbone networks, specialty fiber applications, and optical components manufacturing largely because of their high accuracy and reliability," says Jason Greene, manager of fusion splicer products for Furukawa America."The portability of the S177A brings the benefits of core alignment to the growing construction of fiber-to-the-home and other space-constrained fiber optic cable installations."

Furukawa美国公司光纤融接机产品经理Jason Greene先生表示，由于具有芯部对准功能的融接机有很高的稳定性和准确性，所以它对于有线电视的安装、骨干网、特殊光纤的应用以及光学元件的生产来说是一种非常重要和必需的工具；而S177A的便携式功能和设计也为不断增长的光纤到家和其它长远距离的光纤安装需求带来了更多的便利。
