  • DEVICE AND METHOD FOR CONVEYING AND LIVE CONTROLLING OF LIGHT BEAMS
    Publication number: 20240337559
    Abstract: Devices and methods for conveying and controlling light beams, in particular for endomicroscopic imaging referred to as “lensless”. The devices and methods apply for example to endoscopic exploration, for example of organs of a living being even when the living being is able to move about freely during the measurement. More particularly, the devices and methods allow measurement of the transmission matrix of an optical fiber while “live”, even though the fiber may undergo changes in configuration.

  • Devices and methods for conveying and controlling light beams for lensless endo-microscopic imagery
    Patent number: 11428924
    Abstract: According to one aspect, the invention relates to a device for transporting and controlling light beams for endo-microscopic imaging without a lens on the distal side comprising a single-mode optical fibre bundle (40) on the distal side, wherein each single-mode optical fibre is intended to receive an elementary light source and to emit a light beam at a distal end; a single-mode optical fibre section (50) arranged at the distal end of the optical fibre bundle and intended to receive the light beams emitted by the single-mode optical fibres of the optical fibre bundle; an optical phase control device arranged on the side of the proximal end of the single-mode optical fibres.
