An optical sensor for detecting objects in an area to be monitored includes a transmitter for emitting light pulses, a receiver for receiving light pulses, and an evaluation unit for determining the distance to an object by means of a transit time for a light pulse to the object. The light pulse is reflected back to the receiver in the form of a receiving light pulse, and the transit time measurement is based on a location in time of a maximum point of the receiving light pulse computed by the evaluation unit.
