Abstract
A method for increasing the resolution of confocal images acquired through an image guide whereof the distal end is associated with an optical head for focusing the laser beam emitted by the image guide in an observation object. For a given position of the optical head, the method includes the following steps: producing a plurality of acquisitions through the image guide, each acquisition being produced for a specific spatial shift of the distal end of the guide image relative to the optical head which remains stationary; transforming the data of each acquisition into a point cloud; registering each scatter plot relative to a point cloud taken as reference; superimposing the thus registered point clouds; and reconstructing a final image from the superimposition. Advantageously, a controlled piezoelectric tube is used arranged about the distal end of the image guide to shift the latter.
