Abstract : This paper proposes that by use of the double- refractive capability of a TeO2 crystal, one can work out inside a TeO2 crystal 2 polarization regions, which satisfy the Dixon Equation as its positive and negative solution. In designing instruments, one can make the high-end of the frequency of the No. 1 group' exactly contact the low-end of the frequency of the No. 2 group so that the frequency band can be effectively broadened. The ranges of the No. 1 group and No. 2 group used in our study were, respectively, 40 - 80 MHz and 80 - 140 MHz and thus the band-width of the deflector would be 100 MHz. This paper also proposes a new type of construction for the electric terminals of sonic-optic transducers, to improve the acoustic attenuation, induced by the scatter-spreading processes of the sound wave modified by truncation which has to go through such processes in the acoustic field during its propagation inside the TeO2 crystal.
