摘　　要：文中讨论了红外声光可调滤光器的设计原理与方法,提出了几种声谐振结构,设计制作了一种在近红外波段(1～3μm,2～5μm)工作的大角孔径TeO_2声光可调滤光器,并对其主要特性:调谐关系、光谱分辨率及角孔径等进行了测定。In this paper the design principle and method of the infrared acoustooptic tunable filter(AOTF) are discussed. Several kinds of acoustic resonaor configurations for reducing the RF power are shown. Meanwhile, a large angular aperture AOTF using TeO_2 crystal is designed and developed for operation in infrared region(1～3μm, 2～5μm), and its main characteristics-tuning relation, spectral resolution and angular aperture are determined.
