  • Patent number: 11163116
    Abstract: An integrated optical beam steering device includes a planar Luneburg lens that collimates beams from different inputs in different directions within the lens plane. It also includes a curved (e.g., semi-circular or arced) grating coupler that diffracts the collimated beams out of the lens plane. The beams can be steered in the plane by controlling the direction along which the lens is illuminated and out of the plane by varying the beam wavelength. Unlike other beam steering devices, this device can operate over an extremely wide field of view—up to 180°—without any aberrations off boresight. In other words, the beam quality is uniform in all directions, unlike with aplanatic lenses, thanks to the circular symmetry of the planar Luneburg lens, which may be composed of subwavelength features. The lens is also robust to misalignment and fabrication imperfections and can be made using standard CMOS processes.

  • Patent number: 10520594
    Abstract: A method and a fibre-optical system for illuminating and detecting an object by light includes in situ calibration of a fibre bundle and disturbance-corrected illumination or disturbance-corrected detection of an object, in particular for endoscopic and microscopic applications, and makes it possible to directly determine the single phase distortion of the light, caused by the transmission by the fibre bundle, in order to calibrate the fibre bundle, and thus provides a possibility for determining the system function of a fibre bundle that is improved compared with the prior art of measuring the double phase distortion. The system function is used for disturbance correction when illuminating or detecting the object.

    Abstract: Described herein are various technologies pertaining to detecting tampering of a seal based upon quantum optical communication via a communications channel comprising the seal. A plurality of pulses of light encoded with random data are transmitted on the communications channel, whereupon they are received and their data values measured. The measured data values of the pulses are then compared to the known transmitted data to determine a correlation statistic between the transmitted and received data values. Tampering with the seal can be detected based upon identifying that the correlation statistic has dropped below a threshold non-tampered level of correlation between transmitted and received values.

    Abstract: An optical waveguide serves for guiding illumination light. The waveguide has a waveguide main body for guiding the illumination light between a main body entrance region and a main body exit region. At least one coupling-out device is provided in the main body exit region. Via the coupling-out device, at least one coupling-out illumination light partial beam is coupled out from the illumination light emerging from the waveguide main body. This is done such that the coupling-out illumination light partial beam can be separated from the rest of the illumination light beam emerging from the waveguide main body. This results in a waveguide having improved possibilities for use when guiding illumination light.
