Abstract
Акустическое устройство, адаптированное для эксплуатации в среде, заполненной газом, для выполнения бесконтактного измерения толщины объекта, подлежащего измерению, или для выполнения бесконтактного определения характеристик среды, размещенной по другую сторону этого объекта. Устройство содержит электроакустический приемопередатчик для выдачи акустического сигнала по направлению к объекту, подлежащему измерению, и приема акустического ответного сигнала и сигнальный процессор для обработки ответного сигнала и определения толщины объекта. Преобразователь имеет акустическую границу раздела приемопередатчик-газ и адаптирован для излучения широкополосного акустического импульса к объекту и приема акустического резонансного ответного сигнала. Сигнальный процессор определяет толщину объекта, подлежащего измерению, или определяет характеристики среды, размещенной по другую сторону объекта, используя быстрое преобразование Фурье (БПФ) резонансного ответного сигнала выше заранее определенного уровня отношения сигнала к шуму.
