Abstract: According to one aspect, the invention relates to a device for transporting and controlling light beams for endo-microscopic imaging without a lens on the distal side comprising a single-mode optical fibre bundle (40) on the distal side, wherein each single-mode optical fibre is intended to receive an elementary light source and to emit a light beam at a distal end; a single-mode optical fibre section (50) arranged at the distal end of the optical fibre bundle and intended to receive the light beams emitted by the single-mode optical fibres of the optical fibre bundle; an optical phase control device arranged on the side of the proximal end of the single-mode optical fibres.

Abstract: According to one aspect, the present description relates to a system for high resolution imaging of an object comprising a fiber bundle (1) comprising an array of optical fiber cores (A), said fiber bundle being adapted to receive a plurality of light beams issued from spatially incoherent point sources of an object; the system further comprises a two-dimensional detector (240) with a detection plane, located at a proximal end of the fiber bundle, adapted to receive speckle patterns, each speckle pattern resulting from the transmission of one of said light beams through at least a plurality of the fiber bundle cores, the ensemble of speckle patterns detected by the two-dimensional detector forming a multiple speckles image; and a processing unit (250) adapted to determine an image of the object from said multiple speckles image.
