Segmented mirror telescope

... There is also a proposal to divide a very large primary mirror into many small pieces, polish them, and later combine them into a single primary mirror. This type is called a segmented mirror telescope, and is exemplified by the two Keck 10m telescopes built on Mauna Kea in Hawaii. There is also a proposal to line up independent telescopes vertically and horizontally, extract light from each telescope through a coude focus, and collect the light beams at a single point to obtain the same light-gathering power as a very large primary mirror, while also using it for interference experiments. ...

…　また超大口径主鏡を多数の小片に分割して研磨し，後からそれらを組み合わせて1枚の主鏡に合成しようという考えもある。この型式はセグメントミラー望遠鏡segmented mirror telescopeと呼ばれ，ハワイのマウナケア山に建設されたケック10m望遠鏡（2台）がこれである。　さらに独立した望遠鏡を縦横に並べて，クーデ焦点を通して各望遠鏡からの光を取り出し，それらの光束を1点に集めて超大口径に等価な集光力を得ると同時に干渉実験に使おうという考えもある。…
