  • Patent number: 10935740
    Abstract: Disclosed is a plug-in connector module having at least one optical waveguide and at least one optical sensor, preferably a photodiode, which is arranged near the optical waveguide. The optical sensor can reliably detect malfunction of the plug-in connector module in good time. Also disclosed is a method for detecting signal losses during signal transmission in an optical plug-in connector module, in which an optical signal is guided through at least one optical waveguide of the plug-in connector module, and the optical signal is scattered in the event of a structural defect of the optical waveguide or dirt on the front surface of the optical waveguide, the scattered light reaching a photodiode and a current or a voltage being produced thereby on the photodiode. If a threshold value of the current or the voltage on the photodiode is exceeded, an interference signal is generated by an electronic evaluation system.

  • Patent number: 10935868
    Abstract: A light steeling system and method for diffractive steering of electromagnetic radiation such as visible light is disclosed. Embodiments of the light steering system include leaky-mode SAW modulators as light modulator devices. The SAW modulators preferably include reflective diffractive gratings. The gratings are mounted to/patterned upon an exit face that opposes an exit surface of the SAW modulator, in one example. Steering of light signals emitted from the SAW modulators in these systems can be accomplished by varying wavelength of light signals introduced to the SAW modulators, and/or by varying frequency of RF drive signals applied to the SAW modulators. In addition, light field generators that incorporate SAW modulators of the proposed light steering system within displays of the light field generators are also disclosed.

  • Patent number: 10921520
    Abstract: Brightness profile data having a number of dimensions is extracted based on image data in a radial direction of an optical fiber, the brightness profile data representing features for each rotation angle of the optical fiber. Machine learning uses training data to create a prediction model that based on the brightness profile data determines a rotation angle of each pair of optical fibers is. The pair of optical fibers are rotated to the determined rotation angle and then fusion spliced. The training data indicates a correspondence relationship between the rotation angle of the optical fiber and brightness profile in the radial direction for each rotation angle of the optical fiber. The prediction model can determine a rotation angle of an arbitrary optical fiber based on brightness profile data of the arbitrary optical fiber.
