The bandwidth and the diffraction efficiency are two important operating parameters of the acousto-optic device, which are incompatible for acousto-optic device designed with single-piece transducer. In order to improve the performance of the acousto-optic device, theoretical studies on the operating characteristics of anisotropic acousto-optic device designed with multi-transducers are carried out. The calculation results show that the contradiction between the bandwidth and the diffraction efficiency of the acousto-optic device can be coordinated efficiently and the octave condition can be satisfied when the number of the transducer reaches 16. Furthermore, the linear relationships between the central frequency and the incident angle as well as detailed operating parameters of anisotropic acousto-optic device with multi-transducers are also determined.
The wideband design of the anisotropic acousto-optic deflectors in different frequency bands is studied. By solving the Dixon equation of the geometric relationships of Tellurium dioxide crystal, the wideband design parameters of the anisotropic acousto-optic deflector at low frequency band and high frequency band are obtained systematically. The research results show that different linear properties of the bandwidth and central frequency can be observed under different frequency band, this research work provide theoretical references for the broadband design of anisotropic acousto-optic deflectors.
