Ultrafast Imaging

Special Issue banner

Scope

Ultrafast imaging is key for the realtime visualization of many transient events in physics, chemistry, and biology. The past decade has witnessed the blossom of new theories and technologies that have significantly propelled ultrafast imaging. The newly developed ultrafast imaging system, in turn, has enabled unprecedented applications in both fundamental and applied sciences that unveil many new scientific discoveries ranging from carrier dynamics, molecular structure and dynamics, and brain functions. To date, ultrafast imaging marks an active frontier both in research and innovation.

This Special Issue will highlight recent advances in theories, technologies, and applications of ultrafast imaging, covering various techniques and probes (e.g., electron, x-ray, optical, and THz). Topics of interest include, but are not limited to, the following:

  • Ultrafast sources (e.g., XFEL, synchrotron, lasers, HHG-based, THz, and electron)
  • Ultrafast gating, cameras and detectors devices (e.g., streak cameras, framing cameras, ultrafast CCD/CMOS cameras, and scintillators)
  • Single- and multiple-shot ultrafast imaging techniques
  • Multi-scale/multi-modal ultrafast imaging (e.g., photography, microscopy, diffraction imaging, and holography)
  • High-sensitivity ultrafast imaging techniques
  • Optical field detection and manipulation technologies (e.g., FROG, and metasurface )
  • Ultrafast spectroscopy and metrology (THz, CARS, SERS,OFC)
  • Ultrafast application in Physics, Chemistry, Biology, Materials Science and Engineering
  • Computational ultrafast imaging
  • Modeling of ultrafast phenomena
  • Machine learning for ultrafast imaging
  • New theories and designs of ultrafast imaging devices or systems
