Abstract: A system for producing a multicore optical fiber includes a source of electromagnetic radiation in a spectral range that is suitable for inducing photopolymerization of a transparent polymer. An arrangement of one or more optical components is configured to concurrently focus the radiation that is emitted by the source on a plurality of elongated regions of the transparent polymer so as to photopolymerize the transparent polymer solely in the elongated regions to increase the index of refraction of the elongated regions such that in the optical fiber that is formed of the transparent polymer after the elongated regions are photopolymerized, each of the elongated regions functions as a core of the optical fiber and regions of the transparent polymer that surround the elongated regions function as a cladding of each of the cores.

Abstract: Multicore fibers and methods are provided to reduce crosstalk between cores of the multicore fibers. Multicore fibers comprise a plurality of coated and/or cladded cores, which comprise an absorbing and/or scattering coating over a cladding of the core; and/or multilayered cladding comprising at least two cladding layers having different refractive indices. Imaging endoscopes may comprise the multicore fibers and be used for medical imaging.

Abstract: A system for imaging through a scattering medium may include a spatial and temporal coherent light source for generating an illumination beam to illuminate an object to be imaged through a scattering medium, so as to project an array of spots on the object; an imaging sensor for capturing an image of the object; a first optical setup to capture light transmitted through or reflected off the object and focus the captured light onto a diffractive optical element (DOE) configured to transmit ballistic photons of the captured light arriving from the object while blocking scattered photons; and a second optical setup for capturing light transmitted by the DOE and focus that light onto an imaging plane of the imaging sensor.

Abstract: An endoscope device comprises a reusable unit and a disposable unit. The reusable unit comprises a receiver adapted to receive image data and the disposable unit comprises an insertion tube. The insertion tube comprises an optical guide to image a distal object and a housing that is adapted to accommodate the reusable unit. The reusable unit is adapted to be disposed inside the housing and to be mechanically secured in it. The receiver is adapted to receive an optical image from the optical guide and to convert it to digital image data.
