| 摘 要： | 在分析了关于非同向声光可调谐滤光器的两种设计理论的基础上,得到了在严格满足切面平行动量匹配条件下,大角孔径可调谐TeO_2滤光器的θ_a-θ_i曲线.所得的曲线明显地修正了Chang的θ_a-θ_i曲线,对TeO_2声光滤光器的正确设计提供了可靠的理论依据.

| Abstract: | Based on the analysis of the design theories1,2] for non-collinear acoustooptic tunable filter (AOTF), this paper analysed and accurately calculated the angular dependence between the acoustic polar angle θa and incident light polar angle θi for TeO2. θa-θi curve satisfied the parallel- tangents momentum- matching condition for non- collinear AOTF with a maximum angular aperture is obtained. The resulted curve obviously improved the θa-θi curve of Chang2], and it provides a solid theoretical basis for the design of TeO2 AOTF. |
