PURPOSE:To facilitate the reading of three-dimensional informations from a specimen, by giving time-deviation potential to the horizontal sweep line of an oblique image. CONSTITUTION:Vertical sweep signals of a vertical sweep signal generator 2 is impressed on an anplifier 5 through a bias circuit 13 in such a manner that a bias is impressed; the amplifier 5 amplifies horizontal sweep signals of a horizontal sweep signal generator 1. As a result, a bias which varies according to vertical sweep is added to the center level of a horizontal-sweep wave which is impressed on a horizontal-sweep-deflecting coil 10 of a cathode-ray tube 12, and thereby the horizontal-sweep wave varies simultaneously with the change of the vertical sweep. Consequently, the horizontal-sweep wave which is impressed on the deflecting coil 10 possesses a duplicated direct-current component, and a three-dimensional image is displayed on the image-display surface of the cathode-ray tube 12. |
