Abstract
Description
また、特許文献2記載の技術は、3つの面が直交する平面コーナーキューブを使用しており、精密な平面コーナーキューブの形成が困難であるという問題があった。
また、特許文献3記載の装置は、2枚の光制御パネルを必要とし、大型の光制御パネルの製造が困難であるので、全体として安価に製造できず、更に大型の光学結像装置の製造は困難であった。
前記光反射溝は、直交する第1、第2の光反射面を備え、前記仕切り壁は上方に向かって幅狭となる抜き勾配が設けられ、一側に前記第1、第2の光反射面とは直交する垂直光反射面を有する。
なお、各光反射面の形成は、例えば、アルミニウム等の反射率の高い金属を蒸着又はスパッタリングの鏡面処理によって形成するが、平板状ブロックの表側にのみ鏡面処理を行えばよい。
図1~図4に示すように、仕切り壁15の高さhと、第1、第2の光反射面13、14で形成される断面直角二等辺三角形の高さaはこれらを区別するために、高さh>高さaのように示しているが、図5~図8に示すように、高さh=高さaとするのが好ましく、製造が極めて容易となる。また、仕切り壁15の上端には平面部を設けるのが好ましく、これによって、仕切り壁15が丈夫になり欠け難く、寸法精度が向上する。
この場合、この透明な平板状ブロック11の上側12は全面的に金属蒸着されているので、光反射溝11aの直角三角形断面だけでなく仕切り壁15の表面にも金属蒸着されて鏡面が形成されている。
この実施例では、第1、第2の光反射面13、14及び垂直光反射面19に当たる光は、空気以外の媒質を通過しないので、光の減衰がなく明るい再帰性反射光を得ることができる。
例えば、対象物Aからの光は、第2の光反射面14の(p1、p2)、第1の反射面13(q1、q2)で反射され、傾斜光反射面16(r1、r2)で反射する。ここで、仮に傾斜光反射面16が第1、第2の光反射面13、14に対して垂直であれば、再帰性反射体として作用し、入射光の方向と反射光の方向が同一となって、対象物Aの部分に集光し、像としては見えない。しかしながら、傾斜光反射面16は、第1、第2の光反射面13、14に対して傾いているので別位置に実像Bを形成する。なお、以上の光路は図7、図8に実線で示すが、模式的に示すので、第1、第2の光反射面13、14、傾斜光反射面16の反射光の角度は正確に示していない(以下の例でも同じ)。
再帰性反射体10において、仕切り壁15が同一方向を向いているのが好ましい。再帰性反射体10の第1、第2の光反射面13、14の方向は合わせるのが好ましいが、同一直線上に並ぶ必要はない。なお、第1、第2の光反射面13、14及び傾斜光反射面16を用いて立体像表示装置を形成する場合も同様である。
この場合、大型再帰性反射体32は小型の再帰性反射体10を構成する平板状ブロック11を並べて形成したものであるので、大型のものができ、かつ各再帰性反射体10の第1、第2の光反射面13、14及び垂直光反射面19は露出しているので、光の減衰が生じ難く、より明るい実像Eを形成できる。
なお、この実施例では、大型再帰性反射体32の中央にハーフミラー33を立設したが、例えば、図10にJ-J’で示すように、大型再帰性反射体32の半分のみを使用することもできる。
また、前記実施例においては、第1、第2の光反射面13、14によって形成される断面直角二等辺三角形の溝は空間であったが、透明の樹脂を詰めることもできる。この場合、光の通過効率は下がるが、埃等が堆積することがなく、容易に表面の掃除ができる。
更には、上記実施例では、平板状ブロックの上側にある金属蒸着面を使用したが、平板状ブロックを透明材料で形成し、上記実施例とは上下を逆にして金属蒸着面を下にして使用することもできる。この場合、透明物質を光が通過するので、輝度が下がるがより平面性の良い光反射面を得ることができる。
また、この再帰性反射体をそのまま利用して立体像表示装置を形成することもできる。
