There is no path difference, and no shift when the interferometer is rotated.

当干涉仪转动时，没有附加光程差，没有条纹移动。

Experiment with He-Ne laser and white light for interference, focus on the fringes of the changes and the two plane mirror and the parallel degree from the relationship.

实验中以He-Ne激光和白光干涉仪为干涉光源，重点讨论条纹的变化与两个平面镜的平行度及距离的关系。

In this paper, Gray code and line shifting structure light were projected to the object. Then the distortion images were got which can reconstruct the 3D model: The images space was divvied into 64 cycles by six sequence image the acquisition, the whole scanning plane has been covered by the mobile fringes, which has been cycled 20 times. With the parameters of two calibration cameras , the image pixels has been matched by the principle of geometry.

本论文的主要研究内容是利用格雷码加线移结构光对物体进行投影，再经摄像机采集到畸变的图像，结合相关算法以实现对物体的三维重构：摄像机采集到的6幅图像序列形成的格雷码将图像空间划分为64个周期，通过20次线条纹的移动完成对整个扫描平面的覆盖，在已获得两摄像机标定参数基础上，结合对极几何原理完成左右图像像素点的匹配。

We have developed many kinds of optical methods to measure the insect flight. For example, a beating force measurement method reduces the uncertainty caused by air turbulence; a flow measurement using a frame straddling technique decreases the interval between exposures of the flow;extracting the weak distorted fringes on the dragonfly wing by a correlation algorithm; measuring the camber deformation of a dragonfly wing using projected comb fringe without hypothesizing that the wing is a rigid plate. By measuring the beating force, wing kinematics and flow, simutantously, we can analyze the relationship among many flight parameters.
