Acousto-optic light deflector with 50 positions

An investigation was made of an acousto-optic light deflector in the form of a water container and a lithium niobate piezoelectric transducer. This deflector had 50 resolvable positions for a laser beam of λ=0.63μ wavelength and the switching time was ~6 μsec. The intensity of the light deflected into a side maximum was 20% of the total intensity and the power consumption in the transducer was ~1.7 W.
