基于AOTF的成像光谱仪是集图像、光谱及偏振信息为一体的新型探测仪器，仪器的光谱传递函数是衡量仪器性能的一项重要指标。介绍了单AOTF型和双AOTF型成像光谱仪的工作原理，利用光学域光谱透过函数，推导了以波数Δv表示的单、双型AOTF光谱传递函数，在工作波段为400 nm~900 nm内，计算对比了单、双AOTF型光谱传递函数，并对影响双AOTF型光谱传递函数的因素进行了仿真分析，最后对仪器参数的选取进行了分析和讨论。结果表明：在入射光极角30°, 声光互作用长度5 mm工作波段下，当双AOTF型成像光谱仪工作中心波长相等时，相比同一工作中心波长时的单AOTF型成像光谱仪，光谱传递函数提高了68%；当工作中心波长不相等时，双AOTF型光谱传递函数并不绝对优于单AOTF型，存在临界值。
