The portion of the light that does not reach the front object can be reflected by a larger
object in the background. If all of the light reflected to the sensor is sufficient, this
object is detected. This can lead to a corruption of the measured value.

3.4.11 Scanning range
The scanning range of the device depends on the remission of the object to be
detected. The better a surface reflects the incident beam back to the device, the
greater the scanning range of the device.
