摘要

摘要设计了一种简单有效的相移装置，利用三波长电子散斑干涉法和三传感器电荷耦合器件相机同时高精度测量三维(3D)变形。所设计的移相器可以同时提供准-π / 2相阶跃的三波长激光器。采用90°步进4帧技术从彩色图像分离的红、绿、蓝通道中提取与三维变形信息相关的多分量相位。根据检索相位图进一步确定了6个导数分量。实验结果证明了该方法的有效性和可行性。

Simultaneous three-dimensional deformation measuring based on a simple phase-shift device combination with tri-wavelength and three-CCD camera

A simple and effective phase-shift device is designed for the simultaneous and high-accuracy measurement of three-dimensional (3D) deformation using tri-wavelength electronic speckle pattern interferometry and a three-sensor charge-coupled device camera. The designed phase-shifter can provide tri-wavelength lasers quasi-π / 2 phase-step simultaneously. Multi-component phases related to 3D deformation information are extracted by a 90 deg step 4-frame technique from the separated red, green, and blue channels of color images. Six derivative components are further determined based on the retrieval phase maps. Experimental results demonstrate the validity and feasibility of the proposed method.
