There are two stages: rough adjustment and careful adjustment. During rough adjustment: the laser optical axis is considered as the normal axis of measurement optical path, and the coaxal measurement system is established. During careful adjustment: the tilt coefficient of WYGO interferometer is considered as the adjustment standard to adjust the objective, so the actual result of the object surface quality is ensured.

调整分为粗调和精调两个阶段，在粗调阶段，以激光的光轴作为检测光路的基准光轴，建立起共轴光路检测系统；在精调阶段，以WYGO干涉仪内部倾斜系数作为调整依据，进行物镜的精调，从而保证检测结果反应真实的物镜面形质量。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise.

由于边缘检测中常用的Sobel算子和Canny算子检测同相轴时对噪声免疫差，常因噪声因素引起边缘信息缺失导致同相轴提取不连续，本文采用中值滤波并对Sobel算子进行改进，对地震剖面图进行预处理，结合均方差自动确定阈值并进行异常检测，提取完整同相轴。

The ordinary edge detection methods such as Sobel and Canny operators are immune to noise, which result in cophasal axes discontinuity due to lack of edge information caused by noise. In order to extract cophasal axes more continuous and immune to noise, a novel approach is developed based on edge detection. Firstly, the median filter and improved Sobel method are used to preprocess seismic section images. Secondly, the threshold value is determined automatically based on variance to detect abnormal information. Finally, the complete cophasal axes are extracted after a post-processing.

"A slip joint consists of outside splines on one shaft and matching internal splines in the mating hollow shaft , the splines cause the two shaft s to rotate together But permitthe two to move endwise with each other."

伸缩花键由在传动轴上的外花键和与之相连的空心轴中对应的内花键组成。伸缩花键使两轴一起转动，也能使两轴相对移动。
