摘要: Coherent diffractive imaging (CDI) as a lensless imaging technique, has been
applied in a wide range of sciences. However it is not compatible with short
pulse lasers, because it is limited with monochromatic illumination. Although
there have been reports on the broadband CDI, the band-width is limited with
10% for robust imaging. In this article, we report a algorithm which is able to
CDI robustly with at least 80% bandwidth. This algorithm is apply to published
experiment data and simulated ultra-broadband data to demonstrate its ability.
This technique enables us to capture the non-repeatable transient dynamics as
short as the laser pulse width, which is one step forward to the ultra-fast
CDI.
