... Astrophysics Group . ... MRAO Telescopes . COAST . COAST A Gentle Introduction . ... The limitations of current technology mean that the largest optical telescopes produced today have collecting mirrors up to 10m in diameter. ... The larger the mirror, the further apart these parts can be, and the sharper the resulting image. One of the most amazing developments in optics this century was the realization that not all the pieces of the telescope mirror need be present at the same time! ...

... Ф ОТОЭЛЕКТРИЧЕСКИЙ ГИД . ... П ринцип действия построенного автором гида основан на определении с помощью фотоэлектронного умножителя (ФЭУ) изменений светового потока от звезды, закрываемой непрозрачной преградой при движении гида. ... Если изображение звезды проецируется на щель, то весь световой поток от нее проходит сквозь зеркало и поступает на фотокатод ФЭУ. ... Если больше половины изображения звезды погружается в щель - скорость начинает увеличиваться, меньше половины - уменьшаться. ...
