| 20080225231 | Device and Method for Measuring the Contrast of the Fringes in a Michelson Interferometer and System for Examination of the Eye Comprising Such a Device - The invention relates to a device, for measuring the contrast of fringes in a Michelson interferometer at full field, comprising a Wollaston prism for diverting two perpendicular incident polarisations into two different emergent directions, said diverting means being arranged within the interferometer as substitute for a single polariser. The device is of application to a Michelson interferometer used in an OCT tomographical system and comprising means for obtaining interferometric contrast without use of a modulation technique or synchronous detection methods. | 09-18-2008 |
| 20080231807 | High Resolution Laterial and Axial Tomography - An in-vivo high resolution lateral and axial tomography system of the retina, is provided, including a Michelson interferometer, generating a tomographical image by full field OCT interference with Z sweeping, adaptive optical correction apparatus, correcting the wave fronts coming from and going to the eye, including a reference source, a deformable mirror and wave surface analysis apparatus, detection apparatus producing an image from an interferometric measurement using the OCT principle and apparatus for focussing the wave surface analyser. The apparatus for focussing are embodied and controlled, synchronously with the Z sweeping to force the deformable mirror to adopt an additional curvature, such as to combine the input light source and detection apparatus at a given depth in the retina. | 09-25-2008 |
| 20090002630 | Eye examination device by means of tomography with a sighting device - A sighting device for an examination by in vivo tomography of an eye of a subject including a viewer controlled by a control system for displaying at least one moving target where the at least one moving target has at least one of a programmable shape and a programmable trajectory, and is visible by the eye of the subject during the examination period to allow the subject to fixate and follow the target with their eye. | 01-01-2009 |
| 20090097806 | MODULAR IMAGING SYSTEM, MODULES FOR THIS SYSTEM AND METHOD IMPLEMENTED USING THIS SYSTEM - An imaging device includes an illumination module comprising at least one emitter for emitting at least one excitation beam; a scanning and injection module comprising an image guide, a proximal end and a distal end of which are linked by a plurality of optical fibers; 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; a detection module comprising a detector for detecting a luminous flux collected at the distal end of the image guide, wherein at least one of the illumination module and the detection module is optically conjugated with the scanning and injection module using a conjugating optical fiber. | 04-16-2009 |
| 20100168610 | MULTI-PURPOSE BIOPSY FORCEPS - A method to perform an endoscopic biopsy includes deploying a mechanical forceps through an accessory channel of an endoscope assembly, deploying an optical probe through the accessory channel to an area of investigation, optically evaluating tissue at the area of investigation, actuating the mechanical forceps to grasp a sample of the tissue, and retrieving the mechanical forceps and the optical probe through the accessory channel of the endoscope assembly. A biopsy apparatus includes a delivery conduit, an optical probe configured to investigate the tissue upon a distal end of an optical conduit extending through the delivery conduit, and a forceps assembly slidably engaged over the optical conduit, the forceps assembly comprising jaws configured to operate between a closed position and at least one open position, wherein the jaws of the forceps are urged into the closed position as the forceps are retracted within the delivery conduit. | 07-01-2010 |
