A quantum mechanics trick: interaction free electron microscopy

Pieter Kruit, Department of Imaging Physics, TU Delft

One of the astounding consequences of quantum mechanics is that it allows the detection of a target without interaction between the probing photon or electron with the target. We are investigating the possibility to apply this trick in the field of electron microscopy to generate images of beam-sensitive specimens. This would be especially useful for increasing the  resolution in cryo-electron tomography which for single objects is now limited to 5-10 nm by radiation damage. I will describe some designs for microscopes in which these measurements could be performed, discuss the limitations and speculate about the use of such microscopes in other fields.
