Abstract: The sensor (10) has an electronics apparatus (13) that generates modulation signal and correlation signals. A radiation source (20) emits radiation. A reception apparatus (40) receives radiation reflected by object (30). A correlation apparatus (60) correlates received radiation or corresponding variable to form correlation values. A difference-forming apparatus (70) forms two correlation values from difference between two of correlation values. A calculation apparatus (80) calculates distance with predetermined linear dependence on two difference correlation values. An independent claim is included for a method for operating a distance sensor.
