RADIATION DEVICE

PROBLEM TO BE SOLVED: To provide a radiation device capable of suppressing deterioration of visibility due to a light scattering body in a light radiation direction, and capable of reducing size and a number of components.SOLUTION: A radiation device 1 comprises: a visible light deflector 40a capable of deflecting visible light Rv which the deflector 40a received from a visible light source, by an optional angle; invisible light deflectors 40b, 40c capable of deflecting invisible light Ri which the deflectors 40b, 40c received from an invisible light source by an optional angle; and a controller 7 for controlling deflection of the respective light deflectors 40a, 40b, 40c and operation of the respective light sources. The controller 7 controls the respective light sources so that the invisible light which precedes in time-variant and the visible light scan a scanning object area, and when the invisible light is scattered by the light scattering body and the controller receives the scattered light, the controller stops emission of the visible light. 【課題】 光の照射方向の光散乱体による視認性の低下を抑制できる照射装置において、小型化及び部品点数の削減を実現する。【解決手段】照射装置１は、可視光光源から受光した可視光Ｒｖを任意の角度で偏向可能な可視光偏向器４０ａと、不可視光光源から受光した不可視光Ｒｉを任意の角度で不可視光Ｒｉを偏向可能な不可視光偏向器４０ｂ、４０ｃと、各光偏向器４０ａ，４０ｂ、４０ｃの偏向と各光源の動作を制御する制御部７とを備える。制御部７は、走査対象領域を可視光と時間的に先行する不可視光とで走査するように各光源を制御し、不可視光が光散乱体で散乱されて生じた散乱光を受光したときに可視光の出射を停止する。【選択図】図１
