Abstract:
1. Endoscopy device comprising: several light guides ( a scanning system optically linked to the proximal ends of all the light guides and arranged to direct an excitation light beam in turn into one of the fibres of said light guides from the proximal end of the light guide comprising said one of the fibres, and a detector arranged for, in response to the excitation beam directed by the scanning system into one fibre, detecting a light beam collected at the distal end of the same one fibre, the proximal ends of the light guides being combined to form a bundle of light guides, the light guides being arranged in such a way that, at the proximal end of the bundle of the guides, an arrangement of the fibers varies from one guide to the other in rotational alignment, translation, spacing, or diameter of the fibers, the device comprising means for extracting, from the beams collected by one or more light guides, a set of light beams collected by several fibres at the distal end of one of the light guides, these extraction means comprising means for implementing an extraction algorithm using a correspondence table between each fibre and pixels of a detector, and/or a correspondence table between each fibre and a moment of the scanning period if the scanning is periodic, such that the extraction means can associate each beam detected by the detector with the fibre from which the beam originates.
