Title
(EN) SCANNING PROJECTIVE LENSLESS MICROSCOPE SYSTEM
(FR) SYSTÈME DE MICROSCOPE SANS LENTILLE À PROJECTIONS ET BALAYAGE
Abstract
(EN)
A scanning projective lensless microscope device comprises a specimen surface, a scanning illumination source with a light element, a light detector outside the specimen surface, and a processor. The scanning illumination source scans the light element to a plurality of scanning locations to provide illumination to an object on the specimen surface. The light detector samples a sequence of sub-pixel shifted projection object images corresponding to the plurality of scanning locations. The processor constructs a high resolution image of the object based on the sequence of sub-pixel shifted projection images and a motion vector of the projections at a plane of interest.
(FR)
L'invention concerne un dispositif microscope sans lentille à projections et balayage comprenant une surface d'échantillon, une source d'éclairage de balayage pourvue d'un élément lumineux, un détecteur de lumière disposé en dehors de la surface d'échantillon, ainsi qu'un processeur. La source d'éclairage balaye l'élément lumineux sur une pluralité d'emplacement de balayage pour éclairer un objet sur la surface d'échantillon. Le détecteur de lumière échantillonne une séquence d'images d'objet par projections à décalage de sous-pixels correspondant à la pluralité d'emplacements de balayage. Le processeur construit une image haute résolution de l'objet en fonction de la séquence d'images par projections à décalage de sous-pixels et d'un vecteur de mouvement des projections sur un plan d'intérêt.
