Noise reduction in speckle photography fringe pattern using digital filtering
The noise sources and model in speckle photography fringe pattern is discussed and a noise filter for this model is designed. By means of orthogonal experiment, the effects of noise, visibility and fringe density on the measuring accuracy of fringe direction and space are analysed in detail.
