Accuracies in EM Measurements
| Some common factors affecting the accuracies of all the EM measurements are:
i) the fluctuation of electron beam current. In general, simultaneous data acquisition is a good technique to avoid such effects so that the data is independent of fluctuations of beam current with time.
ii) the specimen drift.
