研究目的
Discussing the technical aspects of X-ray holography from an end user perspective, focusing on obtaining high quality images in a short time, and addressing key challenges such as sample design and fabrication, beam requirements, suitable end stations, and pump-probe dynamic imaging implementation.
研究成果
X-ray holography is a powerful technique for high resolution dynamic imaging, offering drift-free imaging and high contrast. The chapter provides insights into optimizing imaging parameters and overcoming key challenges, paving the way for future developments in the field. The perspective of improved cameras and higher X-ray intensities suggests the possibility of almost live imaging in the future.
研究不足
The technique requires complex sample fabrication and is currently limited by the absence of permanent holography end stations with user support. The intensity of light required for single-shot imaging with high temporal and spatial resolution can lead to sample evaporation. Pump-probe imaging requires perfect reproducibility of the dynamics in the specimen and precise timing between excitation and photon pulses.
