Abstract

The set of equations describing the acousto-optic diffraction problem and bounding the amplitudes of transmitted and diffracted light and their solution that determined the optical wave amplitudes at the acouto-optic tunable filters output is presented. Based on this feature the acoustic intensity of different transducer geometries is calculated, the sidelobe of AOTF can be reduced by changing the transducer geometry and it is proved by experiments. Furthermore by calculating the acoustic intensity distribution of different transducers, optimum transducer geometry is designed..

Keywords

Sidelobe, Acoustic intensity distribution, Transmission function.
