The sensor (10) has a light receiver i.e. photodiode, converting received light into an electric signal. An evaluation unit determines a position of an object in a monitored zone of the sensor from the electric signal. The evaluation unit provides a safety output based on recognition of a protected field intrusion. The evaluation unit recognizes borders of a path (104) from the electric signal, and dynamically fits a rectangular protected field (102) into the borders. The evaluation unit varies angle of rotation and offset of the protected field (102). An independent claim is also included for a method for monitoring environment of a vehicle. |
