摘要：
We explore different 3D imaging techniques suitable for topographical measurement of partially reflective metal surfaces produced in an additive manufacturing environment. Three candidate techniques are investigated: digital holography, ptychographic coherent diffractive imaging, and structured light. The pros and cons of each method in terms of applicability in the AM environment are discussed. Selected simulation results and experimental findings are reported.
