Данное направление перспективно для эффективного обнаружения целого ряда критически важных для безопасности людей газов.</p></abstract><trans-abstract xml:lang="en"><p>It is developed and experimentally investigated the waveguide optical chemical absorption-type sensor based on waveguide structure beingformed on the substrate of lithium niobate Y-cut to control the level of gaseous substances, particularly ammonia. Design of the sensor with the threshold of sensitivity significantly below 0.2 mg/m3is offered. This problem is promising for effective detection of a number of gases critically important for human safety.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>экология</kwd><kwd>абсорбционный химический сенсор</kwd><kwd>волноводный оптический элемент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ecology</kwd><kwd>chemical absorption sensor</kwd><kwd>waveguide optical element.</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">Каттралл Роберт В.
