    Abstract: A black and white display is produced by projection using a scanning argon laser beam operating at 4,880 A and a phosphorescent screen of cerium-doped yttrium aluminum garnet which emits a broad range of frequencies centering about 5,500 A. The yellowish cast of the phosphor output is compensated by a small amount of reflected blue argon light.
