Предлагаемое отклоняющее устройство содержит электронно-лучевую трубку, образует градиент поля, который уменьшает тенденцию большой оси пятна луча к удлинению на каждом углу, на каждом торце горизонтальной оси и на каждом конце вертикальной оси экрана дисплея относительно пятна луча в центре экрана дисплея. Стигматор пятна луча вынуждает пятно луча быть по-существу анастигматическим в каждом углу, на каждом конце горизонтальной оси на каждом конце вертикальной оси экрана дисплея. По одному из вариантов изобретения предусмотрено средство для образования первого неоднородного поля, вызывающее линзовое действие и содержащее изменяющуюся в зависимости от времени часть поля, которая не образуется отклоняющими катушками; средство содержит квадрупольный дублет.The proposed deflecting device contains a cathode ray tube, forms a field gradient that reduces the tendency of the major axis of the beam spot to lengthen at each corner, at each end of the horizontal axis and at each end of the vertical axis of the display screen relative to the beam spot in the center of the display screen. The beam spot stigmator causes the beam spot to be essentially anastigmatic at each corner, at each end of the horizontal axis at each end of the vertical axis of the display screen. One of the variants of the invention provides a means for the formation of the first inhomogeneous field, causing a lens effect and containing a part of the field that varies with time, which is not formed by deflecting coils; The tool contains a quadrupole doublet.
