摘　　要：基于声光可调谐滤波器(Acousto-Optical Tunable Filter,AOTF)的多频工作模式,提出了一种成像光谱系统光谱响应可编程的技术.阐述了该技术的原理方法,介绍了光谱可编程的测试结果,包括对滤光波长、光谱分辨率及滤波通带形状的软件控制.在此基础上,研制了一套光谱可编程成像光谱系统的原理样机并进行了初步的成像实验.通过实验结果证明了该技术的工程可行性和技术优势,为提高成像光谱系统的效率和灵活性提供了一种新的途径.Based on the multi-frequencies mode of Acousto-Optical Tunable Filter （AOTF）, the technique of spectral programmability for imaging spectrometer has been proposed. The principles of this technique were presented, and the test results of spectral programmability were introduced, including controls on the filtered wavelength, spectral resolution and passband shape of AOTF via software. Then a prototype system of spectrally programmable imaging spectrometer was established. Primary imaging experiments was carried out to validate the engineering feasibility and technical advan- tages of the technique. A novel method was provided for increasing the efficiency and flexibility of imaging spectrome- ters.
