Ultrafast imaging is key for the real-time visualization of many transient events in physics

chemistry

and biology. The past decade has witnessed the blossom of new theories and technologies that have substantially propelled ultrafast imaging. The newly developed ultrafast imaging systems

in turn

have enabled unprecedented applications in both fundamental and applied sciences that unveil many new scientific discoveries ranging from carrier dynamics to brain functions. To date

ultrafast imaging marks an active frontier in both research and innovation.
