摘　　要：本文对声光可调滤光器(AOTF)的设计理论进行了深入的研究,提出了在各种不同工作波段内完整的晶体取向参数,得出了实用的“晶体取向准则”;对大角孔径AOTF的特性进行了讨论,并且从本质上分折了大角孔径型和声增强型滤光器在设计方法及性能上的异同点。In this paper the design theory of acousto-optie tunable filter(AOTF)is studied deeply. The crystal orientation parameters for various operating regions are presented and the crystal orientation standard has been obtained. The characteristics of AOTF with large angular aperture are discussed. The similarity and dissimilarity are also analysed essentially in design method and performance for two kinds of filter structure: a large angular aperture type and an acoustically enhanced type.
