Quantitative phase-sensitive imaging in a transmission electron microscope

Ultramicroscopy. 2000 May;83(1-2):67-73. doi: 10.1016/s0304-3991(99)00174-6.


This paper presents a new technique for forming quantitative phase and amplitude electron images applicable to a conventional transmission electron microscope. With magnetised cobalt microstructures used as a test object, we use electron holography to obtain an independent measurement of the phase shift. After a suitable calibration of the microscope, we obtain quantitative agreement of the phase shift imposed on the 200 keV electrons passing through the sample.
