用频谱分析的观点对相移扫描莫尔的方法进行了分析,提出了该方法的付里叶描述.对变形条纹的间隔抽样能分离出莫尔条纹,但这样所得的莫尔条纹精度不高,通过多帧相移叠加能提高精度.揭示了该方法获得清晰光滑的莫尔条纹的频域实质
From the viewpoint of spectrum analysis, the method of phase shift scanning Moore is analyzed, and the Fourier description of this method is proposed. The Moiré fringes can be separated from the sampling of the fringes of the deformed fringes. However, the moiré fringes obtained in this way are not highly accurate, and the accuracy can be improved by multi-frame phase-shift superposition. Reveals the frequency domain of the method to obtain a clear and smooth moire fringes
