摘要
本文提出一种新型三维形貌测量方法，该方法通过投影装置将剪切干涉条纹投射到物体表面，以获取调制光栅图。采用相位法，由计算机生成虚拟接收光栅，从一幅调制光栅图重建物体形貌。文中给出了实验结果和性能分析。
A novel approach to measure and reconstruct the shape of 3-D objects is presented.Themethod is based on the principle of phase-measuring profilometry with shearing interferometryinstrument and virtual grating。The 3-Dshape is reconstructed from an image of deformed fringes.Experimental results and a performance analysis are presented.
