Abstract:
1. Method for increasing the resolution of confocal images acquired through an image guide constituted by a plurality of optical fibres, the proximal end of this image guide being connected to a laser scanning device provided for emitting a laser beam into each optical fibre of the image guide and collecting each return beam during an acquisition, the distal end being associated with an optical head for focusing the laser beam emitted by the image guide in an object under observation, characterized in that, for a given position of the optical head, this method comprises the steps of: carrying out a plurality of acquisitions through the image guide, each acquisition being produced for a given spatial shift of said distal end of the image guide relative to the optical head, transforming the data of each acquisition into a point cloud weighted by the optical power measured on the object through each optical fibre of the image guide, positioning each point cloud relative to a point cloud taken as reference, superimposing the thus positioned point clouds, and reconstructing a final image from this superimposition.
