Abstract

本発明の展開型反射鏡は、展開トラスを構成する複数の伸縮部材間に渡設され、サーフェスケーブルに張力を付与したときに伸縮部材に生じる座屈モードの腹に対応する部分と節に対応する部分とを連結する連結部材を備える。また、サーフェスケーブルを内側サーフェスケーブルと、その外周に結合される外周サーフェスケーブルから構成し、内側サーフェスケーブルは、剛性が高く、張力の変化による長さ変化が小さいケーブルを用い、外周サーフェスケーブルは内側サーフェスケーブルに比べて、剛性が低く、長さの変化による張力変化が小さいケーブルを用いる。内側サーフェスケーブルは、外周サーフェスケーブルを介して展開トラスから張力を付与され、所定の鏡面形状を形成する。
