Paper Abstract

Based on the analysis of the design theories for noncollinear acousto-opto tunable filter (AOTF) by considering the birefringence and the rotatory property of TeO2 crystal, this paper analyzed and accurately calculated the angular dependence for noncollinear AOTF between the acoustic polar angle (Theta) (alpha ) and the incident light polar angle (Theta) (iota ). The calculation pointed out that the approximation for the birefringence and the rotatory property of interaction material leads to an error more than 10% in the optimum incident angle for TeO2 at the wavelength of 6328 angstrom. This error will seriously degrade the design performances of the device. The resulting curves of various operating wavelengths obviously modified the original curve of Chang and it provided a theory basis for the device design of AOTF with large angular aperture.
