Summary
This set of Matlab codes reproduce the figures and experimental results published in our paper: Holographic Phase Retrieval and Optimal Reference Design. David A. Barmherzig, Ju Sun, Emmanuel J. Candes, T.J. Lane, and Po-Nan Li.
• Folder ref_scaling to reproduce Figure 7.
• Folder alg_compar to reproduce Figure 8.
• Folder mimi_compar to reproduce Figure 9.
• Folder flat_mi_compar to reproduce Figure 10.
• Folder ref_deconv contains code to run the Referenced Deconvolution algorithm and compute the expected error for a given specimen and reference. The code is contains a special, optimized implementation if the reference is specified to be a pinhole, slit, or block.
o Ref_Deconv_fcn is a function implementing the Referenced Deconvolution algorithm.
o Ref_Deconv_tester is a sample file implementing Ref_Deconv_fcn.
o ref2mtrx is a function which generates the matrix M_R for any given reference R
o img_recov is a function which recovers a given specimen from the top-left quadrant of the cross-correlation of the specimen and a given reference.
• Folder HIO contains code to run the HIO algorithm
o HIO_fcn is a function implementing the HIO algorithm.
o HIO_tester is a sample file implementing HIO_fcn.
• Folder ref_HIO contains code to run the HIO algorithm, with the reference pixels enforced as an additional constraint (i.e. an additional projection)
o Ref_HIO_fcn is a function implementing HIO with the reference enforced.
o Ref_HIO_tester is a sample file implementing Ref_HIO_fcn.
