Paper Abstract

A photographic cathode ray tube (CRT) recorder in which the displayed information of two cockpit displays are simultaneously recorded via a slave 2-inch CRT is described in this paper. One display is a 5-inch storage tube and the other is a 9-inch CRT Writing speeds on both displays vary greatly and two shades of gray are required. The recording is further complicated by adjacent overlapping lines in the storage tube display in which exposure to film is increased by as much as 100 times. Proper film exposure is achieved by the control of the slave 2-inch CRT beam current to compensate for line overlapping and writing speeds. Because both displays appear simultaneously, resolution and magnification must be weighted to produce the best compromise for information transfer.
