| description | To suppress an aerial image from decreasing in luminance while making a device thin in a configuration of forming the aerial image using a beam splitter and a retroreflective sheet.SOLUTION: An aerial video display device forms a real image of an object in the air by retroreflecting light which is emitted from the object and reflected by a beam splitter, by a retroreflective sheet, transmitting the light through the beam splitter, and guiding the light to a space on the opposite side to the object about the beam splitter. The aerial video display device comprises a deflection optical element 4 which deflects and guides the light from the object to the beam splitter. The deflection optical system 4 has a light-transmissive flat plate member 41 and a plurality of reflective deflection planes 42 arranged apart from one another in the flat plate member 41. The plurality of reflective deflection planes 42 deflect by reflection light from the object which is incident from one plane 41a between two opposite planes of the flat plate member 41 and emit the light from another plane 41b.SELECTED DRAWING: Figure 4
【課題】ビームスプリッタおよび再帰反射シートを用いて空中像を結像する構成において、装置の薄型化を図りつつ、空中像の輝度低下を抑える。【解決手段】空中映像表示装置は、被対象物から出射され、ビームスプリッタで反射された光を、再帰反射シートで再帰反射させてビームスプリッタを透過させ、ビームスプリッタに対して被対象物とは反対側の空中に導くことにより、被対象物の実像を空中に結像させる。上記空中映像表示装置は、被対象物からの光を偏向してビームスプリッタに導く偏向光学素子４を備える。偏向光学素子４は、透光性の平板部材４１と、平板部材４１の内部に互いに離間して配置される複数の反射偏向面４２とを有する。複数の反射偏向面４２は、平板部材４１の互いに対向する２面のうちの一方の面４１ａから入射した被対象物からの光を反射によって偏向して、他方の面４１ｂから出射させる。【選択図】図４ |
