Особенность предлагаемой оптической схемы состоит в том, что измерительный и опорный лучи формируются идентичными оптическими элементами, составляющими опорный и измерительный каналы, при этом оба канала выведены в измеряемую среду. В такой оптической схеме отпадает необходимость введения поправки на изменение коэффициента отражения поверхностей оптических деталей, соприкасающихся с морской водой, при погружении прибора в море, или проведения сложной калибровки с использованием особо чистой воды. В результате появляется возможность использования калибровки прибора на воздухе для определения показателя ослабления непосредственно в измеряемой среде после погружения прибора в воду. Т.к. измерения фактически выполняются на двух оптических базах, может быть выполнена самокалибровка прибора без использования аттестованной эталонной воды с известными оптическими характеристиками. В качестве источника светового излучения применен мощный многоэлементный семицветный светодиод.</p></abstract><trans-abstract xml:lang="en"><p>A compensatory approach aimed at eliminating methodological errors in the measurements of the beam attenuation coefficient in seawater is proposed and the scheme of the transmissometer in which this approach is implemented is described. The special feature of the proposed optical scheme is that the measuring and reference beams are formed by identical optical elements that make up the reference and measuring channels, while both channels are transmitted to the measured medium. Since the measurement and reference channels are identical and both are transmitted in the measured environment, there is no need to correct changes of reflectance on optical parts when the device is immersed in sea water. There is also no need for complex calibration using pure water. As a result, it is possible to use the instrument calibration in air to determine the beam attenuation coefficient after immersion of the instrument in water. Since the measurements are actually performed on two optical bases, self-calibration of the device can be performed without the usage of pure water with known optical characteristics. A powerful multi-element seven-color LED is used as a light source.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прозрачность</kwd><kwd>прозрачномер</kwd><kwd>спектральный показатель ослабления света</kwd></kwd-group><kwd-group xml:lang="en"><kwd>beam transmittance</kwd><kwd>transmissometer</kwd><kwd>spectral beam attenuation coefficient</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания по теме № 0827-2019-0002 «Развитие методов оперативной океанологии на основе междисциплинарных исследований процессов формирования и эволюции морской среды и математического моделирования с привлечением данных дистанционных и контактных измерений»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mueller J.L. et al.
