利用条纹反射技术可以方便地实现镜面反射表面的动态全场三维传感。单视场条纹反射测量系统是一种简单的测量装置。在加窗傅里叶脊法条纹解调技术的辅助下，只需一个十字光栅就可以重构出物体表面的三维形貌变化。合适的校准使得能够确定实际的三维表面轮廓。水波变化的实验结果表明，所提出的方法的可行性。2011美国光学学会Optical Society of America
Dynamic full-field three-dimensional sensing of specular reflective surfaces can be conveniently implemented with fringe reflection technique. A monoscopic fringe reflectometric system can be adopted as a simple measuring setup. With the assistance of the windowed Fourier ridges method as an advanced fringe demodulation technique, only one cross grating is needed to reconstruct the three-dimensional surface shape changes. A suitable calibration enables determination of the actual three-dimensional surface profile. Experimental results of water wave variations are shown to demonstrate the feasibility of the proposed approach. (C)2011 Optical Society of America
