      <abstract xml:lang="ru">
        <p>Причины возникновения оптической окраски сегнетоэлек- трических монокристаллов титаната бария различны. Напри­мер, окраска, определяемая примесями, появляется в про­цессе их кристаллизации; дихроическая — в результате абсорбции проходящего через кристалл поляризованного света. Специфическая окраска монокристаллов возникает так­же в результате интерференции распространяющихся в кри­сталле обыкновенного и необыкновенного лучей, а также вследствие дисперсии и дифракции света ...</p>

        <p>The causes of optical coloration of ferroelectric single crystals of barium titanate are different. For example, the color determined by impurities appears during their crystallization; dichroic — as a result of the absorption of polarized light passing through the crystal. The specific coloration of single crystals also occurs as a result of the interference of ordinary and extraordinary rays propagating in the crystal, as well as due to the dispersion and diffraction of light...</p>
