Is there a way to measure the magnitude of a dislocation burger's vector via high precision optical microscopes?

I need to calculate the size or magnitude of the burger's vector of a dislocation in crystalline materials, metals. Obviously and typically, it can be measured via XRD or the electron microscopy methods, TEM and SEM. The question is:

could it also be measured via high precision optical microscopes, as precise as 1nm ?

instability induced by incoherent twin boundary in nanotwinned copper

1. Strain hardening and softening in nanotwinned Cu:

Nanotwinned Cu foils with about 99% coherent twin boundaries (TBs) among all the boundaries were made. These coherent

TBs, with an average spacing of 25 nm, were engineered approximately parallel to foil surfaces. Low plane-strain deformation

enhances the hardness by refining microstructure and introducing dislocations. High plane-strain deformation results in crystallographic

lattice rotation and reaction between dislocations and coherent TBs, and induces incoherent TBs, thus twin coarsening and

Position within ERC Strarting Grant MINATRAN in Univ of Erlangen

There is a postdoctoral research postition within Dr. K.E. Aifantis's ERC Starting Grant at the Univ of Erlangen. The project is concerned with examining dislocation_interface interactions through gradient plasticty and simulations. A PhD in materials engineering is required and publications in the field must be evident. If a good experimental candidate is found who can perform in situ TEM/nanoindentation experiments he/she will also be considered. The position needs to be filled asap and can be extended for 18 months.

Post-doc, JRC-Petten: Microstructural characterisation of materials and mechanical property correlation

The Joint Research Centre of the European Commission,Insitute for Energy (IET), in Petten Nehterlands, is looking for a motivated scientist or engineer at post-doctoral level to work on characterization of primarily metallic materials for nuclear reactors using a combination of techniques such as scanning and transmission electron microscopy (SEM and TEM), energy-dispersive X-ray spectroscopy (EDX), Xray diffraction (XRD), and 3D X-ray tomography.  (see attachment)
