    Introduction Les travaux de John Bartier sur les gens de justice et de finances des ducs de Bourgogne, ceux de Jean KerhervĂ© sur les gens de finances de l’État breton Ă  la fin du Moyen Âge ou bien encore ceux de Guido Castelnuovo sur les officiers et la sociĂ©tĂ© politique savoyarde Ă  la fin du Moyen Âge tĂ©moignent de l’intĂ©rĂȘt suscitĂ© par l’étude du personnel des princes territoriaux, Ă  l’instar des travaux consacrĂ©s aux serviteurs des rois. Toutes ces recherches, et bien d’autres encore, ont ..

    Simple X-ray speckle-pattern correlation interferometer

    Speckle-pattern correlation interferometry (SPCI) is a well established technique in the visible-light regime for observing surface disturbances. It has found application in non-destructive testing of materials, as well as in medicine. A method of performing SPCI in the X-ray regime is presented. Instead of using surface reflection, small-angle scattering is utilized. The simple geometry consists of one coherent X-ray beam passing through two samples. The calculated resultant speckle field shows highly enhanced sensitivity to relative motion of the samples. Motions are simulated and their corresponding correlation patterns are calculated. Initial experimental results are presented
