  • Patent number: 12130387
    Abstract: A photon detecting 3D imaging sensor device for detecting a distance information for pixels in an image includes an array of detector units. Each detector unit is configured to receive a light signal pulse and to provide a detection signal pulse on receipt of the light signal pulse.

  • Publication number: 20230288687
    Abstract: A method for operating a light microscope comprises emitting and guiding a plurality of illumination light beams towards a specimen (6) to form a plurality of separated illumination light spots (2A, 2B, 2C, 2D) at the specimen; and guiding detection light beams (11) coming from the illumination light spots (2A, 2B, 2C, 2D) to a detector (10) comprising a plurality of sensor arrays (31-34). Each sensor array (31-34) comprises photon-counting detector elements (40), and detection light beams (11) from different illumination light spots (2A, 2B, 2C, 2D) are guided to different sensor arrays (31-34). Measured signals from the sensor arrays (31-34) are analysed to determine positional information about the light spots (15) on the sensor arrays (31 -34). It is adjusted where the light spots (15) hit the sensor arrays (31-34) based on the positional information. A corresponding light microscope is furthermore disclosed.
