Single-shot broadband phase retrieval with coherent modulation imaging

ABSTRACT

Coherent diffraction imaging (CDI) is an alternative way to achieve high performance, obviating the necessity for high-quality imaging lenses. A high degree of coherence of the source is essential for CDI. Coherent modulation imaging (CMI) improved CDI's algorithmic convergence and applicability to general samples. Here, we proposed a single-shot broadband phase retrieval method to increase the tolerance to low temporal coherence by employing the deconvolution approach with the CMI. The feasibility of broadband coherent modulation imaging (bCMI) was verified with optical experiments. This work could pave the way for implementing CMI on laboratory x-ray sources or electron microscopes.
