Optical Distance Measurement Device with Calibration Device to take Cross-Talk into Account
First Claim
1. A measurement device for measuring an optical distance of an object, the measurement device comprising:
- an emission device configured to emit a first signal towards the object;
a modulator device configured to modulate the first signal;
a reception device configured to detect a second signal;
an analysis device configured to receive and analyze the second signal; and
a calibration device configured to calibrate the measurement device with the modulator device turned on and with the emission device operated below a pre-definable power threshold value.
