В соответствии с разработанной схемой собран макет прибора, на котором проведены испытания по оценке его дрейфа на неподвижном основании. Определена зависимость дрейфа ИВОГ-МДЛП от температуры. По результатам испытаний погрешность оценки угловой скорости вращения составила 0,05°/ч, однако при этом выявлена повышенная чувствительность прибора к изменению абсолютной температуры.</p></abstract><trans-abstract xml:lang="en"><p>The paper describes an interferometric fiber-optic gyroscope (IFOG) of a new configuration, i.e., with a birefringence modulator (IFOG-BRM) is proposed. According to the proposed scheme, a prototype model of the device has been assembled and tested to estimate its drift on a stationary base. Dependence of the IFOG-BRM drift on the temperature has been determined. According to the test results, the error of angular rate estimation is 0.05 deg/h; however, high sensitivity of the device to the absolute temperature variations has been revealed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Интерферометрический волоконно-оптический гироскоп</kwd><kwd>модулятор двулучепреломления</kwd><kwd>диффузия титана</kwd><kwd>дрейф ИВОГ-МДЛП</kwd><kwd>температурная чувствительность.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Interferometric fiber-optic gyroscope</kwd><kwd>birefringence modulator</kwd><kwd>titanium diffusion</kwd><kwd>IFOG-BRM drift</kwd><kwd>temperature sensitivity.</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">Sagnac, G., L’éther lumineux démontré par l’effet du vent relatif d’éther dans un interféromètre en rotation uniforme, Comptes rendus de l’Académie des Sciences, 1913, vol. 95, pp. 708–710.</mixed-citation><mixed-citation xml:lang="en">Sagnac, G., L’éther lumineux démontré par l’effet du vent relatif d’éther dans un interféromètre en rotation uniforme, Comptes rendus de l’Académie des Sciences, 1913, vol. 95, pp. 708–710.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Sagnac, G., Sur la preuve de la réalité de l’éther lumineux par l’expérience de l’interférographe tournant, Comptes rendus de l’Académie des Sciences, 1913, vol. 95, pp. 1410–1413.</mixed-citation><mixed-citation xml:lang="en">Sagnac, G., Sur la preuve de la réalité de l’éther lumineux par l’expérience de l’interférographe tournant, Comptes rendus de l’Académie des Sciences, 1913, vol. 95, pp. 1410–1413.</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">Мешковский И.К., Стригалев В.Е., Дейнека Г.Б. и др.
