摘要
提出了一种基于立方体分光棱镜的干涉投影傅里叶变换轮廓术。基于杨氏双缝干涉原理,对立方体分光棱镜的干涉投影理论进行理论分析和仿真实验,通过调节立方体分光棱镜的安装角度可实现干涉投影条纹周期的任意调节,结果证实了该干涉投影系统的可行性以及灵活性。对小脚丫模型进行了三维面形重构,结果表明:干涉条纹相位稳定且强度分布均匀,利用所提方法可以很好地恢复物体的三维形貌。
Abstract
An interferometric projection Fourier transform profilometry based on cube splitting prism is proposed. The interference projection theory of cube splitting prism is theoretically analyzed and simulated based on Young's double-slit interference principle. By adjusting the installation angle of the prism, any adjustment of the interference projection fringe period can be realized. The results prove the feasibility and flexibility of the interference projection system. The three-dimensional shape reconstruction of a small foot model is carried out, and the experimental results show that the interference fringe phase is stable and the intensity distribution is uniform, the proposed method can be used to recover the three-dimensional shape of the object well.
