  • Patent number: 11579264
    Abstract: An optoelectronic sensor, including a transmitting unit for transmitting a plurality of optical signals in each case to a plurality of segments of an object, and a receiving unit that includes a first multichannel analog-digital converter device, including: an analog-digital converter unit; a plurality of signal processing channels, the signal processing channels of the plurality of signal processing channels in each case including: a detection antenna for receiving optical signals; and a modulator for generating an individual signal encoding. Signals of the plurality of signal processing channels, with individual signal encoding, are transmittable together to the analog-digital converter unit, are converted, and may be associated once again with the corresponding signal processing channels due to the individual signal encoding via algorithms.

  • Patent number: 11467078
    Abstract: A particle sensor is described. The particle sensor includes a laser module having a laser, and a detector configured to detect thermal radiation. The particle sensor has an optical apparatus that is configured to focus laser light proceeding from the laser module into a first spot and is configured to focus thermal radiation proceeding from the first spot into a second spot, a radiation-sensitive surface of the detector being located in the second spot, or behind the second spot in the beam path of the thermal radiation focused onto the second spot.

  • Patent number: 11422239
    Abstract: A LIDAR sensor, including: a transceiver-array, which includes a plurality of optical-transceivers, the transceiver-array being a switched-array photonic integrated-circuit, each of the optical-transceivers being set up to in each instance take in a first scanning-spot in a first field-of-view of the LIDAR sensor; a microlens-array which has a plurality of microlenses, the microlens-array being disposed in an optical path of the LIDAR sensor in front of the transceiver array, one each of the microlenses in the optical-path being situated in front of one each of the optical-transceivers; a lens that is disposed in the optical-path in front of the microlens-array; and an optical-scanning-unit which is equipped to alter an optical-beam-path, that starts from one of the optical-transceivers, so that in each instance, a second scanning-spot in the first field-of-view of the LIDAR sensor is sensed by the optical-transceivers, the first scanning-spots lying between the second scanning-spots.

  • Publication number: 20220003657
    Abstract: A method for operating a particle sensor. The particle sensor includes a laser module having a laser, and a detector configured to detect thermal radiation, an optical element positioned in the optical path of the laser of the laser module. The optical element is configured to focus laser light emanating from the laser module onto a spot, and the detector is positioned in the particle sensor in such a manner that it detects radiation emanating from the spot. The method includes subjecting the output signals of the detector to filtering, by which output signals generated by particles not sufficiently heated are excluded from further evaluation. A control unit configured to operate the particle sensor is also described.
