ØAbstract
  
Coherent x-rays generated from recent advanced x-ray sources such as next generation
synchrotrons토토 승무패and토토 승무패x-ray lasers토토 승무패provide토토 승무패new토토 승무패opportunities to apply토토 승무패x-rays in a similar
manner as visible laser beam. One of the most important applications of coherent x-rays
is the new microscopy토토 승무패technique based on토토 승무패static토토 승무패coherent토토 승무패diffraction토토 승무패measurements.
The ultimate토토 승무패resolution of this토토 승무패diffraction토토 승무패microscopy can be in sub-nanometer토토 승무패scale.
In this presentation,토토 승무패we introduce the principle of coherent diffraction imaging including
image reconstruction and phase retrieval.토토 승무패In addition,토토 승무패we present our recent results on
coherent x-ray diffraction imaging using hard x-rays, soft x-ray laser, and optical laser
beam. The impact of the future coherent토토 승무패x-ray토토 승무패imaging토토 승무패would be토토 승무패great토토 승무패in토토 승무패molecular
biology and nanoscience since the structural evolution of a specific molecule or a particle
can be followed in a proper time scale.
