Классические микроэлектромеханические акселерометры миниатюрны, но подвержены электромагнитным помехам, а их метрологические характеристики недостаточно стабильны. Традиционные волоконно-оптические датчики на базе волоконных брэгговских решёток или интерферометров Фабри-Перо обеспечивают высокую чувствительность, однако отличаются сложностью оптической схемы, крупными габаритами и высокой чувствительностью к температурным дрейфам, что затрудняет их интеграцию в системы навигации, авионики, космической техники. Разработан оптический преобразователь линейного ускорения на основе управляемых связанных оптических волноводов. Функциональная схема преобразователя включает чувствительный элемент, источник оптического излучения, фотоприёмники, преобразователи «ток – напряжение» и дифференциальную схему обработки. Предложена математическая модель, описывающая зависимость коэффициента связи оптических волноводов от механических напряжений, индуцированных ускорением. Модель учитывает влияние фотоупругого эффекта. Проведено математическое моделирование работы преобразователя при различных геометрических параметрах конструкции чувствительного элемента. Проведены экспериментальные исследования оптического преобразователя линейного ускорения, которые подтвердили достоверность предложенной модели: достигнута чувствительность 10,5 мВ·с2·м–1 при нелинейности не более 0,68 % в диапазоне ускорений ±200 м/с2. Показана работоспособность преобразователя на основе оптического разветвителя со сплавными волноводами. Такой преобразователь может быть выполнен также на основе планарных связанных волноводов.</p></abstract><trans-abstract xml:lang="en"><p>Various linear acceleration transducers are reviewed, and their advantages and disadvantages are noted. Classical microelectromechanical accelerometers are miniature but susceptible to electromagnetic interference, and their metrological characteristics are insufficiently stable. Traditional fiber-optic sensors based on fiber Bragg gratings or Fabry-Perot interferometers provide high sensitivity but are characterized by complex optical schemes, large dimensions, and high sensitivity to temperature drifts, which hinders their integration into navigation, avionics, and space technology systems. An optical linear acceleration transducer based on controlled coupled optical waveguides has been developed. The functional scheme of the transducer includes a sensing element, an optical radiation source, photodetectors, current-to-voltage converters, and a differential signal processing circuit. A mathematical model is proposed describing the dependence of the coupling coefficient of optical waveguides on mechanical stresses induced by acceleration. The model takes into account the influence of the photoelastic effect. Mathematical modeling of the transducer operation was performed for various geometric parameters of the sensing element design. Experimental studies of the optical linear acceleration transducer were conducted, which confirmed the validity of the proposed model: a sensitivity of 10.5 mV·s2·m–1 was achieved with nonlinearity not exceeding 0.68 % in an acceleration range of ±200 m/s2. The operability of the transducer based on an optical splitter with fused waveguides has been demonstrated. Such a transducer can also be implemented using planar coupled waveguides.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микрооптоэлектромеханичесий преобразователь</kwd><kwd>линейное ускорение</kwd><kwd>чувствительный элемент</kwd><kwd>связанные оптические волноводы</kwd><kwd>показатель преломления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microoptoelectromechanical transducer</kwd><kwd>linear acceleration</kwd><kwd>sensing element</kwd><kwd>coupled optical waveguides</kwd><kwd>refractive index</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Akbaba C.
