Abstract

PURPOSE: To establish the image display unit having excellent sight field selection function.
CONSTITUTION: The signal from the signal detector such as scanning type electronic microscope is applied to the cathode ray tubes 2,3 as the luminance modulation signal through the signal amplifier 1. On the other hand, the sweep signal from the sweep generators 6,7 is fed to the deflection coil 4 of the cathode ray tubes 2,3 through the amplifier 5. Further, this signal is synthesized with the sweep signal which is changed for the amplitude and level with the level setter 14 through the attenuator 9 and with the original sweep signal by means of the mixer 12, and the synthesized signal is fed to the deflection coil of the mirror body through the magnification setter 13. On the other hand, in the cathode ray tubes 2,3, when blanking is made to one cathode ray tube, no blanking is made to another. Then, alternate blanking to horizontal sweep is made.
