Abstract

An analysis to estimate the effect of transducer apodization and discontinuities in acousto-optic devices is presented. Theoretical and experimental results show that a transducer sectioned with oblique cuts does not increase side-lobe levels while cuts normal to the optical propagation direction produce objectionable side-lobes far from the central peak.
