Summary:To reduce the intensity of an electromagnetic wave reflected by a reflector and received by a receiver.SOLUTION: A transmission unit 110 transmits an electromagnetic wave. A movable reflection unit 120 reflects an electromagnetic wave transmitted from the transmission unit 110. A reception unit 130 receives an electromagnetic wave reflected by the movable reflection unit 120 and reflected by an object O located outside the sensor device 10 and an electromagnetic wave reflected by the movable reflection unit 120 and reflected by a first reflector 210. The first reflector 210 is disposed so that a direction in which an electromagnetic wave reflected by the first reflector 210 and received by the reception unit 130 is reflected by the first reflector 210 differs from the direction in which an electromagnetic wave reflected by the movable reflection unit 120 and made incident on the first reflector 210 is mirror reflected by the first reflector 210.SELECTED DRAWING: Figure 2 【課題】反射体によって反射され、かつ受信部によって受信される電磁波の強度を低減する。【解決手段】送信部110は、電磁波を送信する。可動反射部120は、送信部110から送信された電磁波を反射する。受信部130は、可動反射部120によって反射され、かつセンサ装置10の外部に位置する対象物Oによって反射された電磁波と、可動反射部120によって反射され、かつ第1反射体210によって反射された電磁波と、を受信する。第1反射体210は、第1反射体210によって反射され、かつ受信部130によって受信される電磁波の第1反射体210における反射方向が、可動反射部120によって反射され、かつ第1反射体210に入射する電磁波の第1反射体210における鏡面反射方向と異なるように配置されている。【選択図】図2
