  • Patent number: 11226301
    Abstract: A thermographic examination device for non-destructive examination of a near-surface structure at a test object includes a heating device for applying heat energy to a surface region to be heated of the test object; a thermal sensor device for detecting a time profile, following the application of heat energy, of a spatial temperature distribution on a surface region to be measured of the test object, the surface region to be measured including the surface region to be heated as well as an outer surface region to be measured which is adjacent to the surface region to be heated; and an evaluator for evaluating the time profile of the spatial temperature distribution so as to detect at least one parameter of the near-surface structure at the surface region to be measured.

  • Patent number: 11115613
    Abstract: A readout arrangement for an image sensor is configured to receive from a plurality of column leads of the image sensor in parallel a plurality of image sensor analog signals describing in an analog manner brightness values detected by the image sensor. The readout arrangement is configured to select which subset of a plurality of analog values represented by the image sensor analog signals or based on the image sensor analog signals is to be stored in an analog memory for further processing, and to cause storage of the selected analog values in the analog memory, or to store the selected analog values in the analog memory.

  • Patent number: 10553636
    Abstract: A pixel cell, and a method of use thereof, the pixel cell including: an output, a photosensor configured to generate a first measuring current in a first measurement cycle and a second measuring current in a second measurement cycle as a function of radiation, an output node, a power storage device configured so that in a first operating mode a current can be injected by the power storage device as a function of the first measuring current, and so that in a second operating mode the power storage device is configured to hold the injected current so that the injected current can be detected at the output node, and a switching unit configured to form a difference between the injected current and the second measuring current at the output node in a reading cycle and to couple the output node to the output.
