Sector Display Scope Using a Flat Cathode-Ray Tube

摘要

The object of the invention is a sector display scope (indicator of sector survey) using a flat cathode-ray tube with a device for obtaining distance scanning. To increase the speed of the scanning and improve the resolving capacity of the indicator an electromagnetic retardation line is used the lead-outs of which are connected up to metallic bands on the surface of a flat cathode-ray tube.
