On the Stability of Reconstruction of Irregularly Sampled Diffraction Fields

Figure 7

Tikhonov regularization reconstruction error 𝑒 versus the regularization parameter 𝛿 for different noise levels 𝜎. The samples are simulated with the B-F generators and the field is reconstructed by the Fourier generators. The samples form a square cluster 100 times smaller than the volume of interest.
