Description

【００１０】
【課題を解決するための手段】
上記の目的を達成するために、本発明の照明装置の第１の態様は、投射型表示装置の光変調手段を照明するために用いられる照明装置であって、光源と、前記光源から入射される光の照度分布を均一化する均一照明手段と、前記光源から射出される光の光軸上に設置され、前記光源からの射出光の光路を曲げ得る可変頂角プリズム装置からなる調光手段と、前記可変頂角プリズム装置からの射出光が入射される偏光変換手段と、を備え、外部からの制御信号に基づいて前記調光手段が制御されることによって前記偏光変換手段から射出される光もしくは所望の偏光の光量が調節可能とされていることを特徴とする。
