    Abstract: The invention concerns a miniature confocal optical head (4) for a confocal imaging system, in particular endoscopic, said head comprising a point source (2a) for producing a light beam (13); a ball lens (12) arranged at the tip of the optical head, partly outside, to cause said light beam to converge in an excitation point (19) located in a subsurface field under observation (14) of a sample (15), the digital aperture of said lens and the dimension of the point source being adapted to ensure confocality of the assembly; and scanning means (10, 211, 22) for rotating the point source so that the excitation point (19) scans said field under observation. The inventive system produces a real-time confocal image (about 10 images/sec.) of very high quality and homogeneous in the entire field (the optical aberrations are constant in the entire field due to the spherical symmetry of the ball lens), and this is achieved through a miniature head.

    Abstract: The present invention relates to an imaging device comprising: an illumination module (1) comprising means for emitting at least one excitation beam; a scanning/injection module (2) comprising an image waveguide (3), the two ends of which, the proximal end (3a) and the distal end (3b) respectively, are connected via a plurality of optical fibres, and scanning/injection means (6) designed to inject the at least one excitation beam in turn into a fibre of the image waveguide (3) and then into the proximal side (3a) of said waveguide and a detection module (4) comprising means for detecting a light flux (14) collected at the distal end (3b) of the waveguide. At least either the illumination module (1) or the detection module (4) is optically conjugate with the scanning/injection module (2) via a conjugating optical fibre (5, 7). The use of conjugating fibres (5, 7) enables the maintenance, repair and updating of the device to be improved. It also enables modal filtering of the excitation beam to be carried out and ensures that the device is confocal.

    Abstract: The method consists in deflecting the excitation signal at a speed corresponding to acquisition of a number of images per second sufficient for real time use and in detecting the fluorescence signal at a detecting frequency corresponding to a minimum frequency for sampling the fibers one by one. The method uses an image guide consisting of several thousands of optical fibers, an excitation signal being emitted by a source, deflected and injected by turns into the optical fibers of the guide, each excitation point of the tissue in the fiber output emitting in return a fluorescence signal collected by the fiber, then detected and digitized to form an image element. The method also provides for the focussing of the beam in the fiber output to excite a subsurface plane to produce a confocal image. The method also provides for the production of a divergent beam in the fiber output capable of exciting a micro-volume of the tissue from the surface.

    Abstract: La présente invention concerne un dispositif d'imagerie, comprenant: un module d'illumination (1) comprenant des moyens pour émettre au moins un faisceau d'excitation; un module de balayage et d'injection (2) comprenant un guide d'image (3) dont deux extrémités respectivement proximale (3a) et distale (3b) sont reliées par une pluralité de fibres optiques, et des moyens (6) de balayage et d'injection agencés pour injecter l'au moins un faisceau d'excitation tour à tour dans une fibre du guide d'image (3) et du côté proximal (3a) du guide; un module de détection (4) comprenant des moyens pour détecter un flux lumineux (14) collecté à l'extrémité distale (3b) du guide. Au moins un parmi le module d'illumination (1) et le module de détection (4) est conjugué optiquement au module de balayage et d'injection (2) par une fibre optique de conjugaison (5, 7). L'utilisation de fibres de conjugaison (5, 7) permet d'améliorer la maintenance, la réparation et la mise à jour du dispositif, et peut en outre permettre de réaliser un filtrage modal du faisceau d'excitation et d'assurer la confocalité du dispositif.
