Abstract: A method to inspect a solid organ in a subject includes introducing a needle in a predetermined area of the solid organ, inserting an optical probe through a lumen of the needle, and imaging the predetermined area using the optical probe. An optical probe to inspect a solid organ in a subject, the optical probe being intended to be positioned in the solid organ through a needle, the optical probe includes an optical fiber bundle, a ferule to protect the distal tip of the optical fiber bundle, the ferule comprising a shank and a head, and a sheath wrapping the fiber bundle and the shank, wherein the head of the ferule has a length adapted for the optical probe to image the solid organ while keeping the sheath inside the needle.

Abstract: The invention relates to a method for measuring the speed of a particle such as a red blood cell moving inside a flow such as a flow of the blood, using a light scanning microscope. The inventive method comprises the following steps: acquisition of an image by x and y light scanning on a plane containing the object; detection on the plane (x, y) of a mark on the plane (x, y); estimation of the speed vg of the object from the gradient thus determined.

Abstract: The system has a deformable mirror placed between a Michelson interferometer and the eye, to compensate geometric aberrations of the eye. A focalization regulating unit regulates focalization of Shack-Hartmann analyzer, and forces the mirror to bend in order to conjugate an input light source and a detector with a predetermined depth point in retina. The unit is controlled in synchronism with scanning of tomography arrangement. An independent claim is also included for an in vivo tomography method for human retina.

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).

Abstract: The invention relates to a method for producing a fluorescent fiber image of a sample, wherein a sample is scanned with the aid of an excitation signal; the fluorescent signal emanating from the sample is detected, wherein the excitation signal and fluorescent signal use the same optical path; the optical path is used to excite at least two fluorophores contained in the sample; a final image is produced, including areas that are colored according to the at least two fluorophores. The multimarking according to the invention makes it possible to simultaneously acquire two images in two different wavelength bands. The system according to the invention can comprise a spectrometer for spectral quantification of the fluorescent signal.

Abstract: An optical head for equipping the distal end of a flexible optical fiber bundle, designed to be urged into contact with an analyzing surface and including optical elements for focusing an excitation signal into a so-called excitation focal point located at a specific depth beneath the analyzing surface and for sampling a signal backscattered by the excitation focal point which is carried back by the fiber bundle. The head includes an optics-holder tube wherein are inserted on one side the distal end portion of the fiber bundle and on the other optical elements, the latter including a plate placed in contact with the end of the fiber bundle whereof the index is close to that of the fiber core and a focusing optical block, an output window being further provided adapted to provide index adaptation so as to eliminate parasitic reflection occurring on the analyzing surface.
