Abstract: A method for ascertaining an optical crosstalk of a lidar sensor. The method includes: emitting a laser light of the lidar sensor, receiving a signal of a light detector of the lidar sensor representing components of the laser light reflected or scattered. The light detector has a first receive region, the extension and position of which on the light detector corresponds to an extension and position of the laser light imaged onto the light detector when a scattering of the laser light is equal to or less than a predefined threshold value. The light detector has a second receive region directly adjoining the first receive region and which detects components of the laser light imaged onto the light detector when the scattering of the laser light is greater than the predefined threshold value.
