Abstract

Вариант реализации изобретения представляет собой устройство для определения параметра, содержащее источник света, выполненный с возможностью излучения оптического сигнала, и интерферометр, содержащий первый узел отражателя, имеющий по меньшей мере одну отражающую поверхность, и второй узел отражателя, имеющий множество отдельных отражающих поверхностей, обращенных к указанной по меньшей мере одной отражающей поверхности. По меньшей мере один из первого узла отражателя и второго узла отражателя может перемещаться в ответ на воздействие, а отдельные отражающие поверхности указанного множества расположены в фиксированном положении друг относительно друга, и при этом каждая отдельная отражающая поверхность определяет свою, отличную от других длину оптического резонатора относительно первого узла отражателя.
