PROBLEM TO BE SOLVED: To provide an optical scanner capable of emitting light for detecting a position of an observer without newly providing a light source.SOLUTION: An optical scanner of the present embodiment comprises: a light source; an incidence optical system on which light emitted from the light source is incident; a light deflector two-dimensionally deflecting the light emitted from the incidence optical system; a screen including an image formation region where an image is formed using the light deflected by the light deflector; and a reflection optical system reflecting part of the light deflected by the light deflector, the reflection optical system being disposed on an optical path of light other than the light incident on the image formation region out of the light deflected by the light deflector.SELECTED DRAWING: Figure 1

    【課題】新たに光源を設けることなく、観察者の位置を検出するための光を照射可能な光走査装置を提供すること。【解決手段】本実施形態の光走査装置は、光源と、前記光源から出射された光が入射する入射光学系と、前記入射光学系から出射された光を2次元的に偏向する光偏向器と、前記光偏向器により偏向された光を用いて画像が形成される画像形成領域を含むスクリーンと、前記光偏向器により偏向された光の一部を反射する反射光学系とを備え、前記反射光学系は、前記光偏向器により偏向された光のうち、前記画像形成領域に入射する光以外の光の光路上に配置される。【選択図】図1
