To provide a stray light monitoring system and a stray light monitoring method capable of grasping a situation in which projection light from a projector is not accurately applied to an original normal position.SOLUTION: A stray light monitoring system includes an optical sensor 11 installed at a predetermined position around a predetermined normal area to be irradiated with projection light emitted from a projector 102 and detecting the light applied to the predetermined position, and a control device 12 connected by wire or wirelessly to the optical sensor 11, and the control device 12 has a function of detecting the occurrence of stray light caused when a predetermined normal area is not accurately irradiated with the projection light from the projector 102 on the basis of the detection signal from the optical sensor 11, such that when the predetermined normal area is not accurately irradiated with the projection light from the projector 102, the projection light from the projector 102 is detected by the optical sensor 11, and the situation in which the projection light from the projector 102 is stray light can be grasped.SELECTED DRAWING: Figure 2

    【課題】プロジェクタからの投影光が本来の正常な位置に正確に照射されていない状況を把握可能な「迷光監視システムおよび迷光監視方法」を提供する。【解決手段】プロジェクタ102から発せられる投影光が照射されるべき所定正常領域の周辺の所定位置に設置され、当該所定位置に照射される光を検知する光センサ11と、光センサ11に対して有線または無線で接続された制御装置12とを備え、制御装置12が、光センサ11による検知信号に基づいて、プロジェクタ102からの投影光が所定正常領域に正確に照射されていないことによる迷光の発生を検知する機能を備えることにより、プロジェクタ102からの投影光が所定正常領域に正確に照射されていない場合に、光センサ11によってプロジェクタ102からの投影光が検知されるようにして、プロジェクタ102からの投影光が迷光となっている状況を把握できるようにする。【選択図】図2
