Single shot multiple phase retrieval in digital holographic interferometry using subspace processing
DOI:10.1016/j.optlaseng.2018.08.012.png)
摘要
En 中文
The article presents a method to estimate multiple phases from a single moire fringe pattern in digital holographic interferometry. The proposed method relies on analysing the holographic moire signal using subspace rotational invariance approach and offers feasibility for single shot multi-component estimation without multiple frames or spatial carrier and high performance against severe noise. Simulation and experimental results demonstrate the applicability of the proposed method.
