The complex includes a high-resolution scanning transmission mode, a high-sensitivity energy dispersive X-ray spectrometer (EDX), a biprism for electron holography
, and a digital camera.
Techniques such as electron holography
, interferometry, scanning probe microscopy, and X-ray focusing are discussed here.
In our days holography is used for data storage , as a holographic memory, protection of documents , as well as for art, holographic interferometry [14-18], interferometric microscopes , electron holography
, acoustic holography, and etc.
Content covers "all aspects of holography and speckle," ASP said, including biomedical applications, optical memories, x-ray and electron holography
, optical scanning, heat and mass transfer, refraction, astronomy and automatic analysis, among Others.
The key to the new diffraction method, which is a type of electron holography
, is its so-called coherent electron source, notes Stephen J.
He has over 14 years of intensive research in the field and is the main editor of the standard reference book "Introduction to Electron Holography
Among the topics are active dopant profiling in the TEM by off-axis electron holography
, dark-field electron holography
for strain mapping, magnetic mapping using electron holography
, in situ characterization methods in TEM, and preparing specimens for semiconductor analysis.
In this emerging technology, called electron holography
, investigators exploit the wave-like properties of electrons to make their observations (SN: 10/15/88, p.
Dennis Gabor (1900-1979) Electron holography
- Gabor is best known for his research in electron optics which led to the invention of holography.
The project is based on the development of electron holography
in the transmission electron microscope.
in Saitama, Japan, developed the high brightness field-emission electron beam and the high-resolution electron holography
