Description
そして、特許文献3には、再帰性反射体として使用される透明体(ガラス、プラスチック)からなるコーナーキューブ(キュービックコーナー体)を多数平面状に並べ、しかも、その頂部を切り欠いて投光口とし、受光口にハーフミラーを形成して、空中に立体像を形成させる立体像表示装置が開示されている。
また、特許文献2記載の技術においても、多数の帯状の平面光反射部をそれぞれ有する第1及び第2の光制御パネルを用いるので、現時点では製造にコストがかかるという問題がある。
直交状態で連続して形成された第1及び第2の光反射面と、該第1及び第2の光反射面にそれぞれ直交して垂直配置された第3の光反射面と、前記第1、第2の光反射面の隣にあって水平配置された第4の光反射面を備え、1)前記画像Aからの光線は、再帰性反射体を構成する前記第1~第3の光反射面を反射し、前記第4の光反射面で向きを変えて前記画像Bを結像するか、又は2)前記画像Aからの光線が前記第4の光反射面で向きを変えて、再帰性反射体を構成する前記第1~第3の光反射面で反射されて前記画像Bを結像させる。
また、第1の発明に係る画像表示装置において、前記第1の透明体と前記第2の透明体を交互に並べて配置することもできる。
第1の発明に係る画像表示装置において、前記第1~第4の光反射面は、金属の蒸着処理によって形成されているのが好ましいが、めっき、スパッターリング、膜貼り等で形成してもよい。
