    Abstract: The present invention causes spatial-mode light emitted from an optical fiber (11), which is a multimode fiber, to pass through a photorefractive medium (13). The photorefractive medium (13) includes holograms for signal separation that are written by irradiation of the photorefractive medium with (i) guide light having a wave front identical to the wave front of signal light having a particular spatial mode and (ii) control light. The photorefractive medium includes holograms recorded in a multiplex manner with use of control light having different incidence angles in correspondence with respective spatial modes. For signal separation, irradiating the photorefractive medium (13) with control light (15) having a particular angle separates signal light having a spatial mode corresponding to the incidence angle of the control light (15).

    Abstract: An optical pulse generator having a high order transfer function that comprises a first and a second nested interferometric modulator, each modulator comprising an optical input, an electrical input, a first arm, a second arm and an optical output. The second interferometric modulator is optically coupled into the second arm of the first interferometric modulator. The optical output of the first interferometric modulator generates pulses at a repetition rate that is proportional to a multiple of a frequency of an electrical signal applied to the electrical input of at least one of the first and second interferometric modulator and at a duty cycle that is inversely proportional to the order of the transfer function of the optical pulse generator. The multiple may be any integer equal to or greater than one.

    Abstract: A three-dimensional optical scanning vision system capable of producing high-resolution images in real-time includes an optical source (100) for pro­ducing a source light beam. The source light beam is directed to a beam splitter (104) which splits it into a local oscillator beam and a signal beam. The local oscillator beam is directed toward a photo­detector (106), while the signal light beam is directed toward a target (112). Light reflected from the tar­get (112) is received by the beam splitter (104) and directed toward a retroreflector (118) which returns the beam to the beam splitter (104) interface. Quarter wave plates (110,116) and the retroreflector (118) insure that the return light beam and the local oscil­lator beam are collimated and have the same polariza­tion state. Mixing the local oscillator beam and the return light beam occurs at the beam splitter (104) interface, thus providing coherent optical detection by the photodetector (106). The photodetector thus provides an output signal providing a high degree of information about the target. The system also includes scanner optics (2) to scan the signal light beam across the target. A processor (20) is also included for outputting a three-dimensional image of the target, and for controlling the scanner optics (2).

    Abstract: Modulateur de lumiere permettant de generer un rayon de lumiere a phase modulee, comprenant une source (10, 11) de lumiere polarisee (51), au moins un et de preference deux cellules a cristaux liquides (12, 13) ayant une fine couche de cristaux liquides nematiques a anisotropie dielectrique positive au travers de laquelle la lumiere polarisee est dirigee pour produire un rayon de lumineux (14) ayant un dephasage correspondant a un signal electrique de modulation qui est applique sur chacune des cellules a cristaux liquides. Les cellules a cristaux liquides ont de plus une polarisation electrique continue (29, 30) appliquee sur les couches (26) de maniere a obtenir les temps de reponse rapides necessaires pour effectuer la modulation de la lumiere polarisee. La demodulation de la lumiere polarisee s'effectue par division (15) du rayon de lumiere module en ses composantes reactives (16, 17) et en developpant un signal electrique (22) correspondant a la difference de phase entre les deux composantes reactives. Un systeme de communication utilisant ces modulateurs et demodulateurs assure la communication en utilisant la lumiere comme milieu de transmission.
