Interaction-free electron optics in free space and quantum electron microscope
This paper focused on the imaging of sensitive samples such as biological ones by high-resolution transmission electron microscopy,which included the developments in the imaging method of electron beam.First,the mechanism of quantum electron coherent imaging based on the interaction-free measurement(IFM)was introduced in detail.Second,demands of the coupled coherent electron source and transportation of coherent electrons were given for electron IFM in free-space electron optics.Quantum electron microscope,established by combining electron microscope with quantum mechanism,can solve the radiation damage of high-energy electrons on sensitive samples in nature,which becomes a milestone in the high-resolution non-destructive testing of sensitive samples.
