Description
Трудность получени высокой линейности или определенного закона нелинейности при магнитном отклонении луча в электронно-лучевых трубках обусловлена тем, что д. отклонени электронного луча требуетс значительна мопшость, а отклон ющие катушки представл ют собой комплексную нагрузку дл генераторов развертки, что затрудн ет управление формой пилообразного тока.The difficulty of obtaining high linearity or a certain law of nonlinearity with the magnetic deflection of a beam in cathode-ray tubes is due to the fact that the electron beam deflection requires considerable trashness, and the deflection coils are a complex load for the sweep generators, which makes it difficult to control the shape of the sawtooth current .
В описываемом способе требуема линейность (закон нелинейности) отклонени луча электронно-лучевой трубки с магнитным отклонением достигаетс путем введени в основные отклон ющие катушки дополнительных катушек с большим затуханием, на которые с формирующей схемы подаетс ток определенной формы.In the described method, the required linearity (the law of nonlinearity) of the deflection of a beam of a cathode ray tube with magnetic deflection is achieved by introducing into the main deflecting coils additional coils with high attenuation to which a form of current is supplied from the forming circuit.
Магнитное поле дополнительных катушек, вли на основное отклон ющее поле, позвол ет корректировать отклонение луча электроннолучевой трубки, при этом дл коррекции требуютс относительно небольшие мощности.The magnetic field of the additional coils, affecting the main deflection field, makes it possible to correct the deflection of the beam of the cathode-ray tube, and relatively small powers are required for the correction.
