Abstract: An endoscopy device includes several light guides (1, 2, 3), each light guide having one or more optical fibers. The light guides are coupled with a sweeping system (4) arranged to direct an excitation light beam in alternation in one of the fibers of the guides from the proximal end of the guide including the one of the fibers. In this way, the proximal ends of the guides may make use of the same sweeping system, whereas the distal ends of the guides may be installed simultaneously in different zones of interest of an object or animal (10) under study for an almost simultaneous observation of the zones of interest. The invention also relates to an endoscopy method used in a device according to the invention. A device and a method according to the invention may be applied to quasi-simultaneous reflectance, fluorescence, multi-photon imaging of several areas of interest.

Abstract: A connector to connect a fiber bundle probe to a light injection module including a tightening cam having an opening of a specified shape adapted to receive the fiber bundle probe, a cam driving coupled to the tightening cam, wherein the tightening cam is configured to translate in response to rotation of the cam driving until the tightening cam is blocked, at least one spring extending between the tightening cam and the cam driving, wherein the at least one spring is configured to resist when the cam driving is actuated by rotation and the tightening cam is blocked, and a locking mechanism to lock the cam driving into a selected position.

Abstract: An imaging device including an illumination module including at least one emitter for emitting at least one excitation beam, a scanning and injection module including an image guide, a proximal end and a distal end of which are linked by a plurality of optical fibers, and a scanning and injection optical system configured to alternately inject the at least one excitation beam into an optical fiber of the image guide from the proximal end of the image guide, and a detection module including at least one detector for detecting at least one luminous flux collected at the distal end of the image guide. At least one of the illumination module and the detection module is optically conjugated with the scanning and injection module by a conjugating optical fiber.

Abstract: A miniaturized optical head provided to equip the distal end of a beam of flexible optical fibers scanned by a laser beam, is designed to come in contact with a sample and to excite the sample confocally. This optical head includes elements for correcting spherical aberrations and focusing members. The focusing members include: at least a first lens (L4) of high convergence associated with a spherical or hemispherical lens (L5) arranged at the distal end of the optical head, and elements for correcting the axial and lateral chromatic aberration provided with a single divergent lens (3b) whose curvature is substantially centered on the pupil of the optical fiber beam and arranged at the exact distance for this pupil for which the conditions of lateral achromatization coincide with the conditions of axial achromatization; this divergent lens being associated with a second convergent lens (L3a) in the form of a doublet (L3).
