Imaging system for medical endoscopic system, which removes honeycomb artifacts from images from multicore optical fibres

An imaging system for a medical endoscopic system for viewing a target including:

• a medical endoscopic system including an insertion instrument terminating, opposite a proximal part, in a distal head, this insertion instrument being provided with a first multicore optical fiber and with a second first multicore optical fiber each having a distal end, a proximal end and a plurality of cores separated by a separating structure, the distal ends of the first multicore optical fiber and of the second multicore optical fiber being located at the distal head of the insertion instrument;
• and
• a device for acquiring and processing images including:
• at least a first illumination source configured to deliver a light beam, in at least a first wavelength spectrum, to the distal head of the insertion instrument;
• at least one imaging sensor configured to receive light beams coming from at least the proximal end of the first multicore optical fiber and from the proximal end of the second multicore optical fiber, the imaging sensor receiving the images from a configuration system to create, on the imaging sensor, images of the target, for which the position of the separating structure of the first multicore optical fiber is different from the separating structure of the second multicore optical fiber;
• an imaging processor connected to the imaging sensor and configured to process the images coming from the first multicore optical fiber and from the second multicore optical fiber, to reconstitute a composite image of the target in which the image of the separating structures does not appear.
