Safety laser scanner and related method for adjusting distance measurements to compensate for reflective backgrounds

A distance measuring device comprising:

• a transmitter configured to generate a light pulse;
• a receiver connected to different amplification channels;
• and
• a controller operably coupled with the receiver to receive the different amplification channels,
• wherein the controller includes:
• a time of flight core configured to determine time of flight information for the light pulse;
• and
• a decider block configured to determine a measurement correction value for the device based on a determination of a presence of a reflective background that is different than a measurement correction value selected for the device when there exists a diffuse background or an absence of a background into a reading field.
