Description
図3は、本発明の一実施形態による光源束305およびリダイレクト・ブロック335の図である。図示のように、リダイレクト・ブロック335は、複数の光源(光源束305)からの光を受けて、個々の光源のビームを変調器320に向けてリダイレクトする、多重リダイレクト・ブロックである。このリダイレクトは、光学素子(例えば、光学素子330および332)によって提供される。光学素子は、例えば、反射器またはビームスプリッタ(例えば、分割ビームの一部分は変調器320に向けられ、その他の部分は第2の変調器に向けられる)(例えば、ある光ビームを通過させ、他の光ビームを同一または同様の光路に反射するように構成されたスプリッタ)とすることができる。光学素子は、該光学ブロックに埋め込まれたミラーまたは銀面とすることができる。また、光学素子は、全反射を生じさせる光学ブロックにおける模様(impression)または他の変化(permutation)とすることもできる。各光路に、1つよりも多くの光学素子(または反射器)を用いることができる。
本発明について、本明細書では、レーザ光で照明する場合に関して説明したが、本発明は、広帯域またはより広帯域の光源(例えば、LED、ナノチューブベースの光源など)を用いて実施することもできる。図面に示す本発明の好ましい実施形態についての説明では、明確にするために具体的な用語を用いている。しかしながら、本発明は、そのように選択された特定の用語に限定されるものではなく、具体的要素のそれぞれは、同様に機能するあらゆる技術的均等物を含むものと理解されるべきである。
