Abstract: The efficiency and bandwidth of an acoustic deflection cell are increased by using two transducers tuned to adjacent frequency bands and buffer member for causing the acoustic waves from the two transducers to propagate in different directions that are separately optimized. A frequency-sensitive switch connects an AC source to only one of the two transducers. The buffer member is designed to minimize or eliminate light deflection by spurious reflected acoustic components.

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.

Abstract: Acousto-optic devices dependent for their operation on lead molybdate (PbMoO4) and related compounds show efficiencies comparable to that of devices made from alpha-iodic acid and superior to that of devices constructed of earlier materials such as lithium niobate. Optical deflectors useful in modulators, switches and correlators are described.
