改进的编码衍射图相位恢复保证

Improved Recovery Guarantees for Phase Retrieval from Coded Diffraction Patterns

David Gross, Felix Krahmer, Richard Kueng

摘要:

在这项工作中,我们分析了随机衍射图案的傅立叶测量的相位恢复的问题。为此,我们考虑最近推出的PhaseLift算法,该算法用凸优化的语言来表达问题。我们提供了需要O(log^2 d)不同衍射图案的恢复保证,从而改进了Candes等人的最近结果。[arXiv:1310.3240],其需要O(log^4 d)不同图案。

英文摘要:

In this work we analyze the problem of phase retrieval from Fourier measurements with random diffraction patterns. To this end, we consider the recently introduced PhaseLift algorithm, which expresses the problem in the language of convex optimization. We provide recovery guarantees which require O(log^2 d) different diffraction patterns, thus improving on recent results by Candes et al. [arXiv:1310.3240], which require O(log^4 d) different patterns.
