A New Optical Surface Measurement Method with Iterative Sparsity-Constrained Threshold Phase Retrieval Algorithm
Figure 4
Results of phase retrieval in different methods: the first row (a) is the original phase data and (b)–(d) are the reconstructed phase of wave field; the second row (e)–(g) is the residuals between the original phase data (a) and the reconstructed phase data; the last row (h)–(j) is a random line of phase data between the reconstructed (blue) and original (red) phase data.
