Abstract

Studies on polarization switching in shear wave Te02 Bragg cells indicate that background rejection through polarization filtering is possible. Theoretical analysis reveals frequency bands with near homogeneous eigenstates suitable for polarization filtering. Experimental results confirm a background scatter reduction of 13 dB with polarization filtering. A total dynamic range of 80 dB has been achieved in an acousto-optic device operating from 40 to 80 MHz.
