开发了新的自动对接方法，设计了基于阈值的折返遍历搜索算法(RTS)与二分数据截断(BTDT)搜索算法，实现了六自由度耦合平台的四自由度的自动对接。折返遍历搜索算法精度高，可设定不同步长实现不同精度要求；二分数据截断算法搜索速度快，可快速接近最高点。实验结果表明，波导器件的纤到纤损耗可在8 min内调节至8~9 dB(包括波导传输损耗，人工对准需在半小时以上才可达到8~9 dB)，耦合系统稳定性可保持15~20 min。与自动测试系统配合使用，在8 min内即可进行2200点的波长扫描与功率扫描，自动耦合系统具有实用性、稳定性和良好效果。

A method based on MATLAB instrument control technology was proposed to realize an auto-coupling system, avoiding complicated and time-consuming manual alignment. A Binary-tree Data-truncation (BTDT) algorithm and Return-traversal Search (RTS) algorithm based on a threshold were designed for single axis searching. Return-traversal algorithm provides a higher accuracy which also achieves multiple kinds of accuracy and BTDT can search faster. Combined with a laser and a power meter, an auto testing system was developed with GPIB technology. The experiments show that insertion loss of tapered fiber can drop to 8~9 dB including the transmission loss of waveguide in 15 minutes while aligning manually usually takes more than 0.5 hour and system can be kept stable in 15~20 minutes. Besides, with auto testing system, scan of wavelength and power can be completed in 8 minutes for 2 200 points. Auto-coupling system has good effect, stability and practicability.
