This new type of projection microscope<\/strong> consists of a celadonite-based electron source, which has a very high brightness but requires operation at a distance from the structure. To compensate for the loss of magnification, an electrostatic lens and a high resolution screen are used. This holographic microscope makes it possible to achieve magnifications equivalent to those obtained in conventional projectors (about x10^6) in the same acquisition time, while working at a microscopic distance between the source and the sample. This allows for a more comfortable working environment and lower loading effects on the object.<\/p>\n

Projection electron holography<\/strong><\/p>\n

This film gives a detailed presentation of low energy projection holographic electron microscopy.<\/p>\n

Produced as part of the “un chercheur, une manip” (palais de la d\u00e9couverte) event on holography in January 2011, this film shows images recorded in real time; what can be seen or manipulated with the projection microscope: effects of magnification, of the electrical polarisation of an object, or of the magnetic field it creates. The film also shows how to obtain an off-axis hologram and how to reconstruct an electron hologram.<\/p>\n<\/div>\n\t\t<\/div><\/div>
