Ptychography (/t(ʌ)ɪˈkogræfi/ t(a)i-KO-gra … Ptychography (/t(ʌ)ɪˈkogræfi/ t(a)i-KO-graf-ee) is a computational method of microscopic imaging. It generates images by processing many coherent interference patterns that have been scattered from an object of interest. Its defining characteristic is translational invariance, which means that the interference patterns are generated by one constant function (e.g. a field of illumination or an aperture stop) moving laterally by a known amount with respect to another constant function (the specimen itself or a wave field). The interference patterns occur some distance away from these two components, so that the scattered waves spread out and "fold" (Ancient Greek: πτύξ is 'fold') into one another as shown in the figure. Ptychography can be used with visible light, X-rays, extreme ultraviolet (EUV) or electrons. Unlike conventional lens imaging, ptychography is unaffected by lens-induced aberrations or diffraction effects caused by limited numerical aperture. This is particularly important for atomic-scale wavelength imaging, where it is difficult and expensive to make good-quality lenses with high numerical aperture. Another important advantage of the technique is that it allows transparent objects to be seen very clearly. This is because it is sensitive to the phase of the radiation that has passed through a specimen, and so it does not rely on the object absorbing radiation. In the case of visible-light biological microscopy, this means that cells do not need to be stained or labelled to create contrast.be stained or labelled to create contrast.

, La ptychographie (du grec ptycho, signifia … La ptychographie (du grec ptycho, signifiant « plier ».) est une technique de microscopie sans lentille. Pour obtenir une image à haute résolution d'un objet, plusieurs figures de diffraction successives sont mesurées en déplaçant l'objet, tout en gardant un fort recouvrement. L'image réelle est reconstituée par itérations successives, à partir des mesures d'intensité du rayonnement diffracté sur l'objet et de la phase des ondes déduite des interférences entre les différentes figures de diffraction. Cette technique a été proposée par Walter Hoppe à la fin des années 1960 pour la microscopie électronique, mais n'a été effectivement montrée expérimentalement que 35 ans plus tard . Pour cette première démonstration, la reconstruction de l'image a été obtenue en utilisant la méthode de déconvolution de la fonction de distribution Wigner (WDF) . Bien que cette approche permette une approche théorique utile de la ptychographie, le nécessaire échantillonnage de Nyquist dans les deux espaces, réciproque et réel, est bien trop complexe et a rendu les expériences plutôt impraticables. L'intérêt pour la ptychographie a été revigoré quelques années plus tard en incorporant des algorithmes itératifs efficaces de récupération de phase, qui itèrent entre l'espace réel et l'espace réciproque à travers des transformées de Fourier et sont basés sur des projections minimisant la distance sur deux ensembles de contraintes qui assurent à la fois, la cohérence de l'image avec les données mesurées et l'auto-cohérence des images reconstruites dans les zones à éclairage multiple.uites dans les zones à éclairage multiple.
