Zusammenfassung:	To provide an optoelectronic sensor which enables better measurement for detecting objects in a monitoring area.SOLUTION: A sensor 10 provided herein comprises: a light transmitter 12 for transmitting transmission light 16; a light receiver 26 for generating a reception signal from received light 22 received from a monitoring area 20; a movable deflection unit 18 for periodically deflecting the transmission light 16 and the received light 22; a control and evaluation unit 32 for acquiring information on objects in the monitoring area 20 based on the reception signal; and an optical direction change element 18 located in the optical path of the received light 22. The direction change element 18 has temperature-dependent beam-shaping properties.SELECTED DRAWING: Figure 1 【課題】監視領域内の物体を検出するためのより良い測定を可能にする光電センサを提示する。【解決手段】センサ１０は、発射光１６を送出するための発光器１２と、監視領域２０からの受信光２２から受信信号を生成するための受光器２６と、発射光１６及び受信光２２を周期的に偏向させるための可動の偏向ユニット１８と、受信信号に基づいて監視領域２０内の物体に関する情報を取得するための制御及び評価ユニット３２と、受信光２２の光路内にある光学的な方向転換素子１８とを備える。方向転換素子１８は温度依存性の光線形成特性を呈する。【選択図】図１
