... 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. ...
