摘要 | Fringe projection profilometry (FPP) is a commonly used tool in the three-dimensional (3D) measurement of diffuse objects in reverse engineering, products online detection, medical diagnosis, etc. However, due to the limited depth-of-field (DOF) of projection-imaging lenses, the contrast of captured sinusoidal fringes will decrease with the increase of defocus, which affects the high-precision acquisition of axial 3D topography. Although the lenses can be designed based on Scheimpflug principle or double-Telecentric optical path to extend the DOF, some problems such as off-Axis aberration, fixed magnification and limited field-of-view are still existing. To overcome the aforementioned drawbacks, FPP with phase-coded optics is proposed in this paper, where the captured sinusoidal fringe patterns are modulated effectively and the projection-imaging DOF of the system is greatly extended. Experimental results demonstrate the effectiveness of the proposed technique. © COPYRIGHT SPIE. Downloading of the abstract is permitted for personal use only. |
